wiki.linuxmce.org/index.php/RaspberryPi has some attempts to get LinuxMCE running on RPi.
Can someone elaborate on why it is not possible to run LinuxMCE on RPi?
Seems like it should.
For some more information check this out: http://wiki.linuxmce.org/index.php/Porting_Raspbian
Currently I have a raspberry pi running as a MD (no AV yet). DCERouter *could* run on a pi, it would not handle media and orbiter regens would be painfully slow. I have not built any of the database requirements to run a pi as a core, nor have I worked out an installation path for a core on rpi as I do not see it as necessary. LMCE needs a beefier system as a core to properly operate.
Or, as hari says, look into agocontrol which is primarily home automation and is intended to run on lower power devices like the Raspberry Pi.
