I feel you.
One of the reasons we don't see a lot of 4e games played online is because there is no real support for it.
Played 3 hours of 4e Reavers of Harkenwold on Roll20 tonight. A skill challenge (trying to recruit the Woodsinger Elves) and 3 battles (2 notably tough) - our level 3 PCs earned 693 XP each!
The Roll20 VTT definitely works great with 4e.
