DM, are you kidding? There are lots of open source clients more popular than that.
Sourceforge supplies a lot of that bandwidth, and so does rpmfind, freshmeat etc...
No reason to have a profit when everyone contributes a little code and a little bandwidth.
Isn't that what true P2P is all about?
Swabby has been more like a software director lately just inserting patches people have sent him. This is cool.
The RIAA can't do anything about open source clients, you can't stop people from modifying and using their own source code. Commercial for profit clients are the weak link.
If some way is found to DOS the network, a patch can be posted and the DOS attack stopped in minutes!
There are free web servers, mirrors, and the Gnucleus "evolver" will shortly be using P2P to distribute updates!

P2P is free! Let's keep it that way!
