I am not a nanotech specialist, may be that is why I am somewhat dubious 
about its capacities. There are some questions about it:

Assume there is one billion molecule in a cell, how much time a nano device 
would take to control and repair them? Seconds? Minutes? Hours? more?

If life is taken as an example of natural nanotech, (something I disagree 
with...) then a nanodevice can't have a finner structure, both life and 
nanodevices are bottom limited by atomic scale. So a nano repair device must 
be nearly as big as a cell. Is this true? if not why?

One nano device can repair only a small number of cells. If it takes three 
minutes to repair a cell and move to the next, at the 5th the first will 
starve to death for 15 minutes and will need a new round of repair work. Is 
this true? if not, why?

If nano repair robots are of cell size and as numerous as cells, how to put 
them all in the body? Where is the room for them? 

How to get them out? if there are tens of lbs of nanodevices, discard them is 
not a simple task it seems.
