[AG-TECH] macbook pro video (vic) troubles

On bended knee and with humility, I beg that Tom Uram's vic2.exe  
please be bundled in the 2.4 distribution of the AccessGrid Toolkit  
installer executable.

It solves this problem.  When the first vic (sometimes the only vic)  
opens, it finds out it is the first (or only) vic and it will use the  
port assigned by the venue serve to send out video streams.  This has  
same effect that rat does on firewalls and will open firewall ports  
to allow returning, incoming video streams on the same port.  
Subsequent vics processes started for the venue session by the client  
will revert to the behavior we're accustomed to seeing (random port  
selected for outgoing stream).  See http://bugzilla.mcs.anl.gov/ 
accessgrid/show_bug.cgi?id=1228 for more information.

The new vic is included in 3.0.2

Making the change to the 2.4 installer would save incredible amounts  
of time lost to multiple end users and their AccessGrid support  
staff.  I'm hoping that it won't take too much time to change the  
installer but I'm confident that the return of total time to the  
community will be a thousand fold.

It would be great to see this "fix" in the UCL-SUMOVER version as well.

Desperately and Humbly yours,

Joe
