No, but I was musing on a general "upload hook" for all uploads. The 
idea is that the Core and all extensions use one central functionality 
to upload files. Within this code there would be hooks or filters that 
could do all kind of stuff: extract data, index data, deny file upload 
because of restrictions on file extension, mime type or file content.

AFIK there are functions in t3lib_div that handle file upload, ie they 
deal with moving/copying from the PHP upload area to the Typo3 temp 
area. Dunno if that's enough, as perhaps some code might not want to 
move the file to the temp area.
