Well I couldn't find anything at all which uses http or https as a
transport protocol for encrypted communications. I did find a useful
port-listing guide http://www.chebucto.ns.ca/~rakerman/port-table.html
which details the port useage of application protocols like SIP, H323,
and other video conf protocols.
The live comms server documentation is here in case you want to review
it :
http://download.microsoft.com/download/f/b/5/fb5bfc5c-8aa4-4503-b905-0bbf78404c6e/LiveCommGuide.doc
They say they can use SIP, RTP with TLS encryption layers. But as you
wil read, SIP uses port 5060 for communincation, and RTP well read
about it here : http://www.cs.columbia.edu/~hgs/rtp/faq.html#ports
I guess it's not unreasonable to suggest that a VPN would be the best
way to get your data over the internet, as at least anything
transported would already be encrypted. You might want to look into
protocols like GRE to do this, though there's a lot of reading to do !
Hope that helps, although we'd need to know more about your intended
application (video ? audio ? internet or intranet use, VPN etc, file
sharing and data transport intentions)
Cheers - Neil.
