Sure. Still subject to change though. We will make more detailed
announcements shortly.

Yes, usually it would...

A full implementation, at least client-side, without accessing any external
libraries, i.e. self-contained within Command, built on top of our tcp://
scheme and encryption engine, which has been further enhanced for Command.
This includes SSLv2, SSLv3, TLSv1, DES, 3DES and ARCFOUR in export strength
(and in the non-export version of Command, 128-bit encryption), schemes for
ssl:// and tls:// (compatible with 'wait and open/no-wait), and an https://
scheme, interoperable with http:// (for redirects between both schemes etc.),
and support for tunneling through socks and generic proxies. Should be
compatible with pretty much any network setup and secure web server out there.
We managed to squeeze all of this into less than 200 kB of additional code
(x86 version) :-).
Features we MAY include (not sure yet -- space/feature trade-off) are
extended error messages, support for ssl/tls server side, and certificate
access/management.

Large parts of the View engine (image! datatype, image refinements for load
and save, ability to save/png images into a binary!, effects and draw
pipeline etc.), useful for dynamic creation of images for web pages in
CGI/FastCGI environments.
Probably no VID or text support though. Text support would require X
libraries and X server access, which are often unavailable on web servers.
No desktop obviously.
