Tim talks about Fantasy Ground here at Gothridge Manor.
All I can add is amen for Fantasy Grounds. Still love sitting around the actual table but using FG II +Skype is golden for keeping your old group together. If you have some buddies that are now scattered across the country pick a VTT and voice chat sofware and see if you can't get back together gaming.
I heard of people successfully using Web Cams to place absent friends back with a regular table-top group. Although it it is a bummer that you couldn't reach out of the laptop screen to steal some chips from the next bowl over.
