I worked with a group of network engineers that were concerned with
the same thing.
I was the first to switch and after I switch I ran a port scan from my
work (with permission)
to check for blocked ports.
The only port that was confirmed to be blocked (at that time) was
inbound port 80.  This was
in May 2006.  I haven't checked recently but I do run a VPN connection
to home for various things
and haven't had any problems.
