I had the same idea; let AC implement the right mauve-structures (the 
Testlet interface) and you will have a runnable test environment.
If javap is too big a dependency; then it is also possible to generate the 
AC class using reflection.  This means you have to write a class that gets 
a list of fully-qualified class-names and then uses reflection much like 
JUnit does.  Only instead of running the tests you write out a Testlet for 
that class.

This would fit nicely with a project I am (still) working on. I intend to 
create one jar file with all the mauve tests and anyone can then use that 
jar to execute each test on their own JVM.  This fits because I doubt we 
want the generated wrapper classes in CVS and I will surely compile/jar 
using the Sun JVM.

The biggest problem I see with this is that the mauve toolkit will only 
compile/run with JUnit in the classpath.  Perhaps some stubs can also be 
supplied to counter this problem.

As Robert said; many have stated that this is a good idea, but nobody really 
supplied any code to actually do it :)
Looking forward to any proof-of-concepts from you!!
