The beowulfers do something like this. All processes on the 
worker nodes appear on the master node (eg in top). Instead 
of /proc you have /bproc. The idea is to make the beowulf 
look as much like a single system image machine as possible. 
What they do with the devices on each machine I don't know. 
However the beowulfers are the most likely to know if it's 
been done.

Another approach is mosix, which can start a job on one 
machine and migrate it to another. Each machine then has to 
know something about other machines (open file handles etc), 
and possibley they know about the devices on other machines 
too.
