Hi Jim,

Check out my article series on this topic:

The first article provides the rationale for using SSTP and provides
information about how the protocol works and packet structure.

The second article is the beginning of the step by step configuration
procedure.

SSTP's major advantage is that it works through firewalls that block
L2TP/IPSec and PPTP. Since the SSTP is essentially PPP/SSL, so there's
an HTTP header that capsulates the payload. Why is this good? Because it
enables SSTP to work through both stateful packet inspection firewalls
AND Web Proxy devices. 

I've been really impressed with the work that the RRAS group has done
with this protocol and if you want to find even more information on it,
check out the RRAS blog at http://blogs.technet.com/rrasblog/

HTH,
Tom
