I'm a big Dresden fan and long time GM who just picked up the game, and I have to say that I'm loving what I'm reading so far.  I'm also looking to eventually run the game online, but have never played over skype.  I've mostly used pbp forums and various wiki's for support.  Are you and your pliends willing to consider a newbie skype gm?

Fantasy Grounds is a VTT (Virtual Table Top) application where a gaming group can get together and play online, instead of gathering around a kitchen table.  It provides a shared "battle map" where the gm and players can move tokens around during a fight, a chat log for sharing biting taunts and Monty Python Quotes with one another, a dice roller, and a bunch of other tools to help play your RPG's online.

There are a bunch of VTT's on the market today, with some being very expensive and others available for free.  But for gamers who have moved away from their gaming group, they are a really nice tool, and a growing part of the RPG market.
