Look at Boost's Mailing List, this two days, Hugo Duncan said to take the Socket in Boost Sandbox CVS.
Hugo Duncan is not too pursuit of perfection, is definitely the old someone complained that he wrote slow (but it is really slow), he has a "i Have MoveD it out of the boost-sandbox Because My Development Has Been Very Slow And i Did Not Want To Give The Impression of Blocking Anyone else Who Had More Time From Developing a "Boost.socket" library ". When cattle cattle has a relationship, it is really disappointing.
Also: The cattle said to move it out http://giallo.sourceforge.net/
"Giallo IS A C Library, Based ON Underlying Os Demultiplexing Methods. The AIM IS TO GET This Accept Into Boost."
