Integrating Kaffe and Mozilla ?

As far as I'm aware there are a number of problems in doing this right now,
the major one being that the current release of Mozilla doesn't have the
much talked about OpenVM interface (or did they change that already?).
Anyway, from what little I know there are two issues in getting Kaffe into
1. Interfacing the thread and memory management models. Mozilla has (or
will have?) a well defined interface to a non-portable OS abstraction layer
and Kaffe needs to be targeted at this too. This is alot easier from
0.10.x onward because of the various thread/gc/os interfaces that have been
added. It should be a matter or writing the necessary interface glue to
plug these in.
2. Pluging the AWT into Mozilla. No my area I'm afraid (Peter Mehlitz
could probably talk about this) but I suspect it's not trivial. The three
options here are (1) interface Sun's AWT to Mozilla, which I think it kinda
pointless since you can't really use Sun's classes with Kaffe (legally that
is); (2) interface Kore's BISS-AWT intergration, perhaps a better
possiblity; or (3) interface to Transvirtual's Core-AWT (okay it's not
actually available yet but it's not too far away) which has been designed
to make this kind of porting much easier.
But aside from the technial issues, I think there might be some legal ones
- you can't embedded GPL code in to Mozilla since this introduces a
licensing conflict. There may be some ways around this (I can think of
some rather hacky technical solutions to keep the two seperate) but for the
moment I think both Kaffe and Japher [pause while he check there site -
yup] suffer from this problem.
But on the techical front it'd be a great project, but I'd wait until the
OpenVM spec is published and Mozilla is released which supports it - and
maybe by then we'll have kaffe 1.0.0 out which would make a better starting
