Can we all just (file) share?

Interesting Business 2.0 Article talks about three services using file-sharing for transferring large files to hopefully end the problems of attaching large files (e.g. photos, video files) to emails. The solutions are Pando Networks, Perenety and WiredReach.

Although the new services use the same (or similar) technology some of us more geeky types have been using (allegedly) to illegally download music and video online, their goal is to create a more user-friendly interface, similar to (or actually using) regular email.

Sounds like an easy transition from this to implementing the same to bolster the biggies' (AOL, Yahoo, MSN) instant messenger services, no?
