  Yep.

  Nope, not yet, but it's under active development at the moment.

  It supports the berkeley sockets API, but relies on the features of the underlying OS to implement it, so it cannot do anything that windows itself does not support (though it may be it more or less easy to access certain functionality using one API or the other).

  There is a bit of overhead, but not a great deal; most of cygwin's implementations of the berkeley sockets APIs are just fairly thin wrappers around calls to the underlying winsock functionality that is used to implement them.
