I've not looked into it in detail, but one shop I worked at had
what they called a "vpn" for remote access (I disputed the name:-)
that was simply socks over SSL.

I can't agree with that, sock is extraordinarily simple, I've yet to
see an HTTP proxy that was as simple. If nothing else HTTP is more
complex to parse.
But I wasn't really thinking about https when I mentioned sock as
handy for adding slightly more control to SSL than port forwarding,
more thinking about other arbitrary apps that encapsulate over ssl,
not an uncommon strategy for various b2b one-offs.
And, speaking of the standard CONNECT method used by http
browsers and proxies to bore https through firewalls, at least
one socks client implementation (Dante's) can route over it.
Of late my favourite socks client is the gloriously simple
connect by Shun-ichi GOTO <firstname.lastname@example.org>, available from
<URL:http://www.imasy.or.jp/~gotoh/ssh/connect.c>. I first learned
about it by searching for how to socksify openssh. Oh, and it can
route over http proxies via CONNECT as well:-).
