Locomotive components (i.e. cilia) will undoubtedly be much simpler (and
smaller) than the components necessary for construction and external
manipulation of materials. It would be interesting to see a simple
specification for a nanite capable of manipulating raw materials, etc...

eek! optics and/or other sensory components - that's pretty bulky too. I
guess the simplest capability would be chemical compounds which react to
certain environmental variables... thoughts?

Is there any data storage technology on the horizon which could conceivably
scale to this degree? Quantum computing is dependant on "atomic" storage,
anybody have info on this?

Agreed - bacterium are certainly small enough for many tasks though. For
example, a nanite this size may not be able to repair cellular nuclei, but
could probably repair tissues...
