any p2p libraries in .net

looking for a p2p library for

peer to peer and peer to peer(S)

so far I've come across

Brunet http://boykin.acis.ufl.edu/wiki/index.php/Brunet   
// does not seem to have #2 above

WCF P2P  http://msdn.microsoft.com/en-us/library/cc297274.aspx
// does not seem to have NAT / UPnP

OpenServer http://openserve.codeplex.com/
// not truly p2p but can be added per owner

ZK++ http://zkpp.codeplex.com/
// DC compatible, not whole lot of info though

Flowlib  http://code.google.com/p/flowlib/
// supports DC/ADC but no activity since Jan 2009 ???

NextHUB http://sourceforge.net/projects/nexth开发者_Python百科ub/
// officially stopped Jan 2010 after no activity in a year !

so the choice is not very clear, Any that i missed ? Are there any commerical .net libraries ?

Any comments on the choices above from personal experience perhaps ?

MonoTorrent

Very much peer-to-peer indeed.

What exactly is your application mean to do? The WCF can handle this properly and grabbing the basics will help you understand what exactly you need and if there's a perfect already available library out there for you.

Take a look at this: http://msdn.microsoft.com/en-gb/library/ms751502.aspx

There's also our MsgConnect available. Doesn't support UPnP but one can add it himself.
