Re: Proposed Aim for Speak Freely

If you want to trasmt music at a better quality it mis more likely that you 
want integrity than real-time . so a tcp trasmission would be bettere, and 
anyway this is not an internet phone application.
You can _optionally_ put other codecs, but for real time telephomy 
saving lag and bandwidth it is a must.
Even if you had a wide bandwidth connection, usng a low bandwidth 
channel would always yeld bettere real time results than larger 
bandwidth ones (consider if in the same wideband connection there are 
other users ....)
