Agreed! Parts of VIC/RAT are worth reusing (eg libcommon) but I think
its time to get rid of the TCL/TK reliance. I think there is enough
people working in the area of video tools for the AccessGrid to start
a community development aimed a replacing VIC in the AG. 

The Argonne group have talked about it, but have their hands full 
on the toolkit. And there are several groups/people who are doing 
video "stuff" in the AG, eg JongWon Kim et al (DV and HDTV), Barz 
(MPEG4 and H.264), Hiroyuki Komatsu (AGPager), Colin Perkins (HDTV), 
us (VP).

Who out there would be willing to contribute to a community driven 
development for a new AG video tool? If there is enough interest then
the new AG Community Portal by Darran might be an appropriate venue
to start from. 

I'm keen to contribute if you didn't realise yet :)

I look forward to it.
