It is likely easier than to have them swim around in the bloodstream or elsewhere - a well defined chemical environment (maybe a bit reactive) with no immune systems attacking them. The nanochondria could be powered by modified ATPases.

The trick is the material; you don't want anything too brittle. You might also want to have osteoclasts that can break it down. Don't forget that the bones are important calcium reserves.

Especially when debugging ufogs :-)

Yes, but bio-inspired nanodevices would be right at home. It is wet, sloppy and random, but has a good infrastructure. The only problem might be that protein-based nanodevices could produce a HLA signal to the immune system.
