Is it possible to grab the id3 metadata from an mp3 file while it's uploading from the user's browser to allow prefilling a form about the users track?

Question

I have this requirement for a site I'm working on:

The business owners want to show users a track form for the mp3 they're uploading as soon as they start uploading it and prefilling the form with the id3 data from the mp3.

I don't see how this is is possible apart from perhaps using custom flash (e.g. SwiffUploader customised to look at the header of the file, do the parsing and send a callback to the js).

Thoughts?
