I already have kickstart files that you can slam to a USB stick, here:http://svn.linuxmce.org/svn/branches/LinuxMCE-0810/src/MeeGo
(these are early versions, feel free to refine them more, if i don't get back to them first.)
This is not the end all be all. the PadOrbiter v2 work is intended as a launching platform for new orbiter tech, but I needed to get the old stuff running on it for now.
These files can be processed by mic-image-creator (MeeGo Image Creator), into complete USB images with the -f liveusb switch, and can be installed onto the device. For now, you will need to attach a USB keyboard to select the Install option at bootup.
The point being, that there is enough here, that any device that runs MeeGo can be turned into an orbiter by writing a kickstart for it.
Do not use orbiterplus, unless you are prepared to dig into it yourself and understand how it works. I will not expound upon it further.
