That would be interesting.  Right now, the RTEMS user scheme is based on 
a somewhat fake version of /etc/passwd and /etc/groups.  You can populate
it however you want.  I suppose you would have to somehow magically 
create a home directory with the files that ssh expects.

I would expect that RTEMS has the infrastructure to support this
but it would require some magic and care setting up the 
files on the RTEMS target.
