The power problem, incidentally, is one of the reasons the OLPC is 
considered to be so crucial.  Its power profile:

* 10 watts going full-bore (heavy networking, heavy display repaints)
* 3-6 watts typical usage
* <1 watt in e-book mode (scrolling only, monochrome display mode)

It might be very interesting to see if it's possible to join the server 
compute power of LTSP with the low-power OLPC client.
