Is it possible to write a javascript SSH client that uses web sockets for transport?

Would it be possible to write a basic SSH client in pure javascript using something like orbited web sockets as the transport layer? I don't see any examples of this, but it seems like it would be a nice thing to have.

You can check out Ajaxterm and rTerm, which uses it.
I really like Orbited and used it on one of my company's internal systems (with RabbitMQ). It should be possible to take the concepts from those applications and use Orbited as the transport layer, though I don't think this is the best use case for it (as the task being single-user and not channel-based etc.).
