No argument. I agree. I think they'd find a _large_ percentage of the
user base went to internet based contact if they had the ability to do
so.

Yeah, I understand that IPSEC doesn't work over 99% of the firewalls out
there (as a passthru).  In that regards, it is a shame they didn't use a
diferent method (http over SSL would have been fine doign it via
webservice).  Oh well.  But like I said, making a requirement to have a
server outside of a firewall to use a service is just so shortsighted.
