Rule #1 - Be Patient - Rule #2 - Don't ask when, if you don't contribute - Rule #3 - You have coding skills - LinuxMCE's small brother is available: http://www.agocontrol.com
Enable it, then tell me the number and I'll let you know. Just kidding, AFAICT that's how the pluto support people were/are able to log into their customers' systems and fix things. I have no idea how it exaclty works and if it even still works.
What can one do over the web as far as controlling linuxmce is just the wap capabilities provided in the mobile orbiter or is there more.
