What can a developer do with my UDID for iPod touch?

A developer is asking for my UDID, and it seems like a pretty sweet deal. almost too good.
what can he do with my UDID that would be negative for me?

The UDID is solely used for the purpose of identifying the device for certain tasks, such as the eligibility to upgrade to new beta firmware or to have your device used to install apps to from developers.

Any developer including myself can do it for free, there's no harm from doing it. You'd be able to upgrade to the new iPhone OS 4 beta.
