mikemuch writes "Huge email attachments should become a thing of the past if these new online file sharing services take hold. A couple, FileCrunch and YouSendit resemble nothing more than online storage with a sharing component. Microsoft's early beta Windows Live Folders is entering the fray, offering a shared folder metaphor, while Tubes is a file-syncing service from mobile platform developer Adesso Systems that keeps files synchronized on the individual sharers' machines. Pando leverages the BitTorrent protocol, but making it private so you can share media with a chosen network of friends and colleagues rather than the whole world. The services all have free levels for file sizes ranging from 50MB to 1GB."
