Completely possible to use headphones with this software; been doing it ever since I got it
As for the cable situation, I can understand your concern. It sounded like you had more control over how much bandwith you had available to you. I my current situation, I have (1) DSL @ 1.5Mbs x 128Kbs and (1) DSL @ 786Kbs x 384Kbs. Between the two and with the help the the Nexland Pro800 Turbo Router, I have a total of ~2.0Mbs x 512Kbs at my disposal. I am hopeful I can get at least a good 16 player C-Strike server going without much problems but I also wanted to host my GameVoice server along side. My server box can handle both but my DSLs might not be able to.... was hopeing to find another dedicated line to run the GameVoice server from so I could maximize the bandwith for the C-Strike server.
Let me know if you change your mind. Thanks
