Hi!
Myself and another developer while on placement have just completed a web app to send large files too large for email attachments and thought we'd release the source to the world, hopefully some of you here will find it of use, or help improve it
It's currently at beta stage and we've done all this in 2 days so if you find any issues please let me know on here or on the issue tracker on Codeplex

Suggestions welcome too, thanks
