The problem with this is that the file would effectively have to be completely read back from the player. This wouldn't be such a problem with Hijack installed -- you could just grab it with FTP, I guess. It would be quite slow over the normal protocol.

On my list of things to do in my copious free time is a VBR fixer that you run on the player at a shell prompt, that would fix up all the duration/bitrate tags in the *1 files as well.
