Adam sent me something he called 0.9.1.  That's not an official release
of the uIP code, Adam has sent me a number of patches.  In fact, the
better base for this is probably Contiki.

I think uIP is easier to port but harder to write applications for.  uIP
can only have a single segment in flight at any moment, so there is no
windowing.  However, uIP's requirements are absolutely minimal and it
conforms to RFC standards.  It has packet reassembly too, which is an
optional compile-in.
