Virtual tabletops
In the past year, one friend in Brooklyn, N.Y., another in St. Louis, Mo., and I (in Boston) have tried a number of things for online role-playing. Fantasy Grounds had a sweet interface, but getting access to the host server through our firewalls was a problem. RPGtonight is a bit simpler, but we've also had refresh issues.
Skype and Whiteboard work fine for most things, but a dice-rolling utility and simple map function would be nice. At the moment, I'm hoping that the D&D4e Insider will be what we need. Recently, RPtools and D20pro have been recommended to me. I'd be interested in learning what those of you who have limited bandwidth and who have tried multiple programs would recommend...
