	I wish I could add Winsock 2 support to libsocket. It's at the top
of my to-do list for libsocket.

	With regard to 1): Specs. Ahahaha. I doubt Microsoft will ever
produce specs for the WSOCK2.VXD device driver. If only they would release
the source code for it <sigh>

	I think Winsock 2 can be accessed from a DOS box. I haven't 
checked it myself, but here is some justification. Dan Hedlund, the author
of the WSOCK C++ library, originally found out how to use WSOCK.VXD
device driver from a DOS box [*]. He is investigating how to use
WSOCK2.VXD. He told me that he has got creation and destruction of sockets
working, but not sending/receiving. So, hopefully he'll work out the
remainder soon, and Winsock 2 support can be added.

[*] libsocket is based on Dan Hedlund's code from his WSOCK library.

	Perhaps the most irritating aspect of this is that WSOCK.VXD from
Winsock 2 is the same (binary compare) as the WSOCK.VXD from Winsock 1.1.
I have no idea why it does not work.
