So this news is rather exciting...http://www.themook.net/gamegeekery/gurps-with-fantasy-grounds/
Basically there are two big players in he Virtual Table Top Market (VTT), Fantasy Grounds and Roll20.
Roll20 is subscription based and uses their own servers so has a few features Fantasy Grounds does not. However the GM needs to pay a small monthly fee.
Fantasy Grounds uses your own computers so has an option for a one time software purchase.
From what I have heard and seen they are pretty comparable but each has thier own strengths and quirks.
However with an automated system FG will be able to save a lot of game prep by allowing faster game prep and some faster online actions. It may even allow import from GURPS Character Assistant which would really save a GM some time.
Create a character in the $15 program (Including NPCs and foes) and export them direct to your online game instead of typing them up.
Also a Fantasy Grounds license will add more visibility to GURPS .
