That might help indeed. We always found somewhat guilty because you had no use 
for our changes to Rudolph, while the Rudolph sources were really helpful to 
us. The reason is that our VMs differ so much. We prefer Java code to C 
because of portability reasons and performance (while JNI calls are 
expensive, we can compile the Java code).

Therefore, our current implementation only uses 5 native methods. We also 
support some frame buffer devices directly (no X needed). If this is useful 
for somebody else, we probably can give that to Classpath as well (provided 
that Acunia offers the Classpath license, of course). I can make no promises 
here, because we have to discuss this first, but personally I see no 
problems.

I've seen that the Classpath AWT implementation uses peers. This has 
advantages on some targets, but is not very helpful on targets without any 
Window System at all. I personally like the idea of having two different AWT 
implementations (at aicas we were already discussing that matter), according 
to the target system. What about the other Classpath developers? Do you thank 
that including two AWT implementations is good or do you prefer having a 
single implementation that should fit for everybody?

Kind regards,

        Andy.
