I have clocked 5 plays so far and it worked better than expected. In fact it recreates the F2F experience satisfyingly , just without the actual F2F part. There is an in-client chat but I suppose Skype or Ventrilo could help further enhance the experience.
But the real kicker is that you get to build a tournament worthy deck and run it out against opponents from all over the world. The former is a boon since finances may hinder one from obtaining sufficient copies of each card while the latter is a boon since AGoT LCG players are far and few where I live.
I have so far only tried it with Ivan and Jo but hopefully I'll soon be able to play against enthusiasts from other parts. Leave a note if you are keen for a game.
