Couple of other questions I'm afraid.

1. Does the Divine Metamagic feat (copied below) let you choose 'any' metamagic feat for it to apply to (when taking the feat) or only a metamagic feat that you already know.

Page 80: Divine Metamagic feat
The boldface text needs to be added to the Benefit
paragraph of the feat description:
When you take this feat, choose a metamagic feat that
you have. This feat applies only to that metamagic feat.
As a free action, you can take the energy from turning
or rebuking undead and use it to apply a metamagic feat
to divine spells that you know. . . .

2. The shield bonus from Two Weapon Defense increases when 'Fighting defensively or taking the total defense option'. Does fighting defensively include the use of combat expertise (as combat expertise mentions fighting defensively as the 'normal' clause). edit: just noticed that for the feat 'Deadly Defense' it has a clause that it applies when using combat expertise to take a -2 penalty or more, not sure what bearing this has on the above question.

So essentially having improved two weapon defense is useless with combat expertise? And two weapon defense itself is even worse.

FAMILIAR POCKET
Universal
Level: Sorcerer/wizard 1
Components: V, S, M
Casting Time: 1 standard action
Range: Touch
Target: One container or garment with a pocket touched
Duration: 1 hour/level (D)
Saving Throw: None
Spell Resistance: No

You move your hand along the mouth of the pocket intended for your familiar, and a line of glowing white energy follows in its wake. The glow fades, and the space seems strangely larger inside than a normal pocket.

When you cast this spell, a garment or container becomes a safe haven for a Tiny or smaller familiar. The spell turns the target pocket into a comfortable extradimensional space (about 1 cubic foot). The familiar can fit inside the space without creating any noticeable bulge in the item. Whenever the familiar is touching you, you can whisk it inside the space as a free action by speaking a command word chosen by you when the spell is cast. If the familiar can speak, it can command itself inside. As a free action, you can call the familiar forth or it can leave the space on its own.
   Once inside, the familiar has total cover and total concealment, and as a free action, you or the familiar can further seal the space to make it airtight and waterproof. The air supply inside the sealed space lasts for 1 hour, but with the pocket unsealed, the familiar can remain inside indefinitely. The familiar cannot attack or cast spells from within the space, but can use supernatural or spell-like abilities as normal (provided they don’t require line of sight, which the pocket blocks). You continue to gain the special ability granted by your familiar. While inside the pocket, the familiar continues to benefit from the share spells ability as if it were adjacent to you.
   The spell ends if the familiar pocket is placed within or taken into another extradimensional space (such as a portable hole). If your familiar is within the pocket when the spell duration expires or if the spell ends abnormally (as above), the familiar appears in your space unharmed.
   Material Component: A tiny golden needle and a strip of fine cloth given a half twist and fastened at the ends.

What exactly are the limitations of a spellsword's channeling class feature?  Can he hold a spell in the sword for a later attack?  Are there any spells he can't cast?  What about chill touch or touch of the graveborn, which allow multiple touches per casting - do they get channeled as seperate melee attacks?  Thanks for your time.

Spontaneous divine casting is not on the list of rules from Unearthed Arcana that we're allowing, so no.

Also no on the feat from the Eberron rules.  If it's from another setting, we're not using it.  Sorry.

I'll see about starting a new AtS thread this weekend.

Variant Character Classes

Variants of certain classes are allowed, as seen in Unearthed Arcana and
elsewhere, but you may not multiclass between variants of the same class.

Double Weapons: Dire flails, dwarven urgroshes, gnome hooked
hammers, orc double axes, quarterstaffs, and two-bladed swords are
double weapons. A character can fight with both ends of a double
weapon as if fighting with two weapons, but he or she incurs all the
normal attack penalties associated with two-weapon combat, just as
though the character were wielding a one-handed weapon and a
light weapon (see Two-Weapon Fighting, page 160). The character
can also choose to use a double weapon two handed, attacking with
only one end of it. A creature wielding a double weapon in one hand
(such as a human wielding a Small two-bladed sword) can’t use it as a
double weapon—only one end of the weapon can be used in any
given round.
