Further research shows that what the product/service that is really
being sold is DynGate.

Sounds like DynGate is a commercial version of Stunnel?

TeamViewer and Dyngate - why are there two programs?
TeamViewer is a remote control software that is based on the VNC
project, or better, on the UltraVNC remote control solution, which is
itself based on RealVNC. TeamViewer is free software and is licensed
under the GPL. So TeamViewer is an open source project. You may download
the complete source, modify it and use it however you like, as long as
you comply with the GPL.
TeamViewer enables remote connections based on a TCP/IP connection over
port 5900. That means, to connect two TeamViewer clients, you connect to
a partner`s PC on port 5900. In many cases this will only be possible
within a local network, firewall settings often deny TCP/IP connections.
Another problem are local IP addresses: Most LANs use NAT gateways to
translate internal IPs to external ones - which makes it very difficult
to connect to a partner within another local network. DynGate is our
solution for that problem: DynGate allows to route any TCP/IP connection
over a http tunnel, which means any traffic is routed like "regular"
internet web site access - which allows almost anybody to connect to PCs
as long as an Internet connection is available! DynGate is a completely
separate software that communicates with TeamViewer just over an
internal TCP/IP socket connection. In later releases DynGate will also
be able to tunnel data connections for other software beside TeamViewer.
