I may be crying wolf, but I see the same potential gotcha that we had 
with gif's all those years ago when they let it become a web std, and 
Compuserve suddenly came up with that submarine patent and demanded a 
rather high priced fee for the use of anything that could generate a 
gif.

The net result being that 95% of the gif's vanished from the web in about 
60 days, and I don't know if I have any survivors on this machine that 
aren't archives from 25+ years ago.  A lot of people lost a lot of 
shirts, having worked on that code for several years.  QT's parents, 
TrollTech, might decide to do the same thing to us.  If what I see being 
committed on github is not to be suspect at some point, I'd sure want 
that OK for it to be both in writing by their legal representative, and 
widely published right along side the gpl in our Docs.

That event I see as a possibility, so I've not made any moves to recreate 
what I've done with pyvcp but using qt's tools. I think it would improve 
the looks of our gui's, but at what potential cost?
