What is the future of Java SSH module - replacement Available?

What is the chance of a replacement? How about open code from putty? Some other suggestions? It is handy to have access to the Linux box in FreePBX.

I have written an alternative but im not sure if we are pushing it yet. We may g9 another route. Know it is on the radar.

Its all about security. Do you have a alternative to suggest that can run inside a browser??? Putty is a executable. Need something browser based and OS agnostic.
