A 32-bit system is pretty much a necessity.  It may be possible to get the 
engine working on a 16-bit processor, as long as it can create and use 
executables greater than 64k in size.

An MMU is desirable, but not necessary.  If the embedded OS has the ability to 
allocate large chunks of contiguous memory, which are fixed in place once 
allocated, then it should be OK.

Operating systems with moveable memory regions that must be explicitly locked 
to access them will probably never work with pnet though.  In that case, get 
a real OS. :-)
