Ability to "Push" access clients to other machines on the same network
LogMeIn had an option in their Rescue product that would allow you to see other machines on the same "segment" by using the computer browser service perhaps and "push" the equivalent of a support session to them via PSExec/scheduled task or something.
It was really helpful for the "crap we thought we had the agent on that machine" scenarios.
We have an extension named "The Client Networker" that will allow you to deploy access clients to other network machines. It's in the final review stages, so you should see it in the extension brower soon.
