1) Edited the poll-header to be less racy.
2) To answer the question...
I ran several sessions of my FTF game via skype due to one or more players being quite sick. Software used was Skype and catchyourhare.com shared screen dieroller.
Currently play in a Burning Wheel Skype game using same software. I want a headset, but can't afford one. Maps are sent as files, usually small PDF's, when needed, tho I'm likely to switch to SVG's. (Smaller files, and can be opened with FF, Chrome, Safari, and Opera; IE can't open them without a plug-in, and Firefox can't open them inline, only as separate files.)
