Maybe
JW Media Player can be used to put full flash support in IP.Gallery.
The player is used on very much websites as alternative for the official expensive Adobe software.
It is available under Creative Commons license and also cheap for commercial use (if IPB would use it in IP.Gallery it cost only once 100 dollar for unlimited use by the customers.)
So I hope you guys can add flash support to IP.Gallery. I get more and more flv movies (from game publishers) so I can just simpely add them to IP.Gallery.
Also by using something like this there could be a nice interface which will blend good into the board skins.
