I'm using VPNs now.  The device makes a VPN connection back to the
server and I use that tunnel to communicate with the bits of software.
This works well, but it means the site has to allow that port open for
outbound.  I'm trying to consolidate it so that one port (80 or 443)
will carry both sync traffic and web (async) traffic.  I've found
Anyterm and it has an Apache module.  I've not done much more digging
to see how that module works.  It could be async that happens fast
enough that the user does not notice.  That would cause performance
issues.  Especially if I try an run a VPN over it.
