I just released the first version of my Javascript secure email service gpgsend.com. The service uses Javascript to encrypt a message using the recipients PGP key, and then my server forwards the message on behalf of the sender. The system will also search pgp.mit.edu for public keys if they’re unknown.
It’d be great to hear what anyone thinks of the service.
