is possible to install a disked md like joggler
The answer to that is yes, but no. Yes the entire LMCE stack will run on the BPi (I have even installed and run a Core on the BPi and RPi2, not that I recommend that). However there is no hardware video acceleration at the moment. There has been some effort to implement a vdpau style acceleration on the BPi but so far I have only seen it function in MPlayer and then only for certain content.
If you're simply looking for UI1 Orbiter control then yes. If you want HD video playback then not at this time. I will admit that I have not looked in the last 4 months to see what has developed in that time. Hopefully in time the vdpau interface will mature and be usable through Xine player.
There are currently no instructions posted anywhere on how to do this so find me in irc and I can help you through testing if you want.

PS. I have questions regarding the asterisk changes you've suggested in a recent ticket. I don't want to hijack this thread for that but if you could find me in irc so we can talk I'd really appreciate it.
