Service to allow users to upload large files

I need an app/service I can put on our web server (LAMP) that will allow external (and unauthenticated) users to upload larg开发者_开发技巧e files (10 MB - 100 MB for now) to our website, instead of trying to email them.

If possible, it should be very user-friendly, as it will be used by non-technical users.

I don't really want to roll my own, as I'm sure this must've been done before, but I'm not sure exactly what to search for. I seem to get a lot of results for torrent servers etc.

I agree with Jens. To help you along, this might help: http://www.plupload.com/

Try using an app called Simple2FTP that is easy and allows visitors/customers to upload files of virtually any size. (they say they have successfully uploaded a 1 + gig file using their app) I think it is simple and pretty flexible enough to allow for a number of different use situations. They are at http://www.Simple2FTP.com and have a free trial you can download.
