WordPress MU

Hello Everyone -
I would like to know if there is a way to upload attachments to a remote server instead of using a local directory ?
Meaning: the option value of "Upload Path" will be: http://www.example.com/files/" and every time a user will create attachment in some post then the attachment file will be stored there rather than in the local directory at the server.
I have searched for a plugin addressing this issue for some time and I haven't found yet.

Would be happy if you'll help me on this one,
it will save me lots of headache

There's a few plugins out there that use AmazonS3 for file uploads. If you were searching on the word "attachment" that's probably why you never foudn any.
