Currently we're focussing all of our efforts on making the best possible Android SSH/terminal client.
That said, we'd love to see JuiceSSH branch out to multiple platforms, with CloudSync keeping all of your connections/settings synchronised between the platforms.
If you've got development experience on any of the above platforms and want to get involved with helping JuiceSSH evolve, feel free to get in touch with us at support@sonelli.com - we'd love to talk ideas/opportunities with you.
