MHP was the reason to start the project at all :)

We've done an AWT 1.1 implementation from scratch, only lightweight, no Button,
ListBox or other peer widgets, only window, image, font and event peers. Too bad
the code is in Nirvana (at least, hopefully). Even without JIT I could run my
jump'n'run testing Xlet in a ~600x300 area with 50 fps using just AWT with one
Paint event after another and all objects in the whole loop being recycled, 
starting
with 12 garbage objects per Frame before getting rid off them step by step. That
was on an embedded MIPS with a simple blitter.

Of course, real user interfaces were also supported and even Swing could run 
with
a few issues that were remaining, some layout update problems at least.

There was a downloadable CD "MHP4Free" or "MHP4All" with our Stack, but only
binaries. Such a CD could be used to extract (decompile) the Java Sources at
least, which I would not want to rewrite, but the native code could be fun and
more fail safe to reimplement.

Maybe it's time to do more investigations regarding the state of the code. It 
would
be great if this could be open sourced after all.
