Good Morning -

I concur on this point.  The firewall ports are really an issue here
at the lab, and in the monthy High Productivity Computing Systems
meetings that we hold.  It was also a problem for me when I was at WPI
and working with folks at UMass Medical School - hospitals are
especially loath to open ports - and port closing is the default - it
will only get tighter.

Just my $0.02
