[boost] Sockets: proposal for a library design

I updated the Wiki pages for a net library at http://www.crystalclearsoftware.com/cgi-bin/boost_wiki/wiki.pl?BoostNet. After collecting all the information I found at the Wiki pages for the socket and multiplexing library I try to explain how a net library should basically look like. The proposal includes various I/O models and is based on I/O streams. As usual any comments are appreciated, Boris
