Linux, or more specifically uClinux and other variations,
support embedded systems with no MMU (Memory Management
Units).  How hard would it be to port NetBSD to them non-MMU's
systems?  What steps, work would be needed?  Has anyone else
attempted this, or is working on this now?

Last I heard,  WindRiver (the embedded systems company) bought
BSDI and hired FreeBSD gurus like Jordan Hubbert create an
embedded BSD OS for them.  Anyone knows what happened on that
front?

Thanks in advance,
Alicia.
