I was thinking something...  Bryce has an option to make a panoramic render for QTVR, so why not expand on this to render to the right format HDRI?

Then if you want a complicated scene for a backdrop, in theory you could use the HDRI instead of throwing your "hero" model into an actual scene. This might be useful for making smaller files, or shorter renders.

Of course someone might also work out a way to make the QTVR panorama into an HDRI (or LDRI) which could be useful, but why not be able to render one in-program?
