Regarding caseless, I only have the SR3 book on hand:
quote:
Firearms are primarily slug-throwers. Many weapons offer
two versions, for standard loads or for caseless ammunition,
though the latter is far more common in the 2060s. A weapon
can fire either type of ammunition,
So yes, caseless is available and generally what I will assume you're using unless you specify otherwise. Yes, gel rounds are available.
As for dataline tap; yes, you can insert a remote data tap HOWEVER it is limited bandwidth. So that will permit you very basic functionality, but not full VR, and that means you're going to be at a very serious disadvantage when it comes to all things decking. Yes, the decker can elect to sit outside of the facility and not put any skin in the game, but that generally means he's not going to be a very good decker.
