This seems almost identical to Sendoid which appears to have died completely. For asynch file sharing, we can use Dropbox, for synchronous file sharing, Skype.

This seems almost identical to Sendoid which appears to have died completely. For asynch file sharing, we can use Dropbox, for synchronous file sharing, Skype. Is there a file size limit on Skype? I must say that when I've seen a very very similar product completely die as recently as Sendoid did, I get pretty sceptical about the viability of the idea.
