I'd second that Graywolf, KFS ran a number of servers for the squad and was kind enough to run one for a m8's Delta Force team. Even on that mega connection though it still suffered from a few stutters, I remember being up late with KFSwith one of the BC guys trying different settings.
The BC guys were snapped up by Microsoft (held in a dank M$ prison cell with no food so I heard
) The fruits of their collective loins ended up as the Sidewinder Game Voice which is a nice little unit with an excellent Plantronics headset which at first I though was a little flimsy but its taken a beating from the kids and still works
The voice quality is excellent but they still need to add a few more features to the voice command function to make it as good as Mindmakers Game Commander2 IMO.
Apparently the new BETA 1.3 for Game Voice is only days away from release and its adds a few more features to the voice command side of the software as well as offering a standalone server solution for those clans/teams/squads blessed with the facility of having their own permanent server.
