Tabletop simulator and GZG games

Does anyone on list have experience with Tabletop Simulator?

Does it handle turn based games well?  Can you save a game half way
through for later?  Any chance we can use it for Full Thrust, SGII or
Dirtside?

(I've gotten sick enough lately that 3-4 hours straight just isn't an 
option anymore.  But 3 or 4 one hour sessions still is.)
