(Creator of Commando.io here) - Thanks for the feedback. Commando.io is very young, and while currently only supports SSH, LDAP could easily be added. The alpha build is extremely minimal, and serves as a proof of concept. However future features are parellel execution, interactive sessions, scp transfers (maybe even Murder transfers [bitTorrent]), and provisioning.

You have to think back, when GitHub first launched, they probably had a minimal product. It takes a bit iteration to add the "eureka" features.
