What we've been doing (those of us playing BC2) is using voice comms through Xfire. It works really well.
I also have it on authority that GSC works well too, but I don't have it installed and have not tried it.
Xfire allows you to configure a permanent VOIP channel on their server. So every time you connect to Xfire, you can then open a voice comm to the VOIP channel you created. Wingman set up ours and he said it was easy.
I recommend that whoever sets it up, name it something like SE_ROF, or SE_Diablo3, or whatever it needs to be for the description of that game. (oh, and use our normal password)
The person who creates it will need to invite other SE's to it, but once you are in that VOIP channel, save it to your favorites and it will always be there.
- * It's almost like being on the telephone.
* You can use PTT, but I don't anymore. (for me, no more worries about pushing a button while in a firefight - granted sometimes people will hear my head getting wanged by a flying +5 frying pan launched from Diabla.)
* It's persistent
* no resources being used to host, only for client.
try it, you'll like it.
