Great idea here. Instead of shuffling between Yahoo! Briefcase, FTP servers and file splitters, just use this to email your big files. When you email a file using a token, the Token software makes your computer a server. I am not sure how well it works across firewalls, but seems like a good idea altogether.

Joel Spolsky's post also announces this as something that we have always needed. The idea is so simple and its surprising that we have overlooked it for so long.

[Update: I guess good things always come at a price. Even though redeeming a token is free (you still need to download the Redeemer - this should be eliminated somehow to make it more usable), creating a token is not. The basic stuff costs $49 and setting up a Token Server is $1000]
