About the patent issue, i found this on the nvidia site : http://code.google.com/p/nvidia-texture-tools/wiki/FAQ Apparently no problem, even in US. So is it ok if i send you a submission in the next few days to use nvidia texture tools into VPB ?

Libsquish is already something I've experimented with but haven't reployed as the result I got were mixed and there is also the patent on the S3TC compression technique which libsquish uses which complicates it's usage.
