Just found this:
MochiBot is a Flash traffic monitoring tool that tracks the performance of individual Flash content files no matter where they end up on the web. Mochibot is completely free and it works very easy. Just put some Actionscript code into your flash file and it will be ready to be tracked.
If you give out FLV's to your affs or provide them to tubes you can track them with this tool.
Just a thought.
