I don't heard of anybody doing that, but:

The entire client install process is controlled by the install script, 
so you can customize it to do only what you really need ant can 
configure systemimager to use your trimmed down kernel in the install 
process to have a working client faster.

I think that the speed of the install will depend of your network 
bandwidth. SystemImager has three transports to image a client: rsync, 
multicast and bitturrent. If you use small images and tweak the install 
script, the install can be faster that the reboot itself.

    Bruno,
    Has anybody tried dynamically reconfiguring the nodes to optimize
    for an application, maybe trimming the kernels down to bare minima
    for quick swichovers? I'm interested in optimization algorithms more
    than in application hosting per se, so it would not need to be real
    fast for expermienting.

        I think this middleware can solve your installation problems:
        http://wiki.systemimager.org/

        You can have several images to be replicated and select a image
        and a
        install script for each machine.
