Here is another similar product called firetalk. This is a copy of a messge from the BgnrBanjo list on Onelist.com

Has anybody checked out Firetalk? It's like Hearme.com, but it's a little more usable and allows for 1 on 1 or group chat without going through a bunch of steps. www.firetalk.com

It looks like it also has a voice pressence on a web site feature. It may have less bugs, just don't know.
