My interest is proportional to the direction that the next revision  
goes.  In order that this work could serve as long as the existing  
MDR has, I would like to see it rewritten from scratch with the  
latest in a few areas:

1) Code generation (if it is still deemed necessary) is done with a  
toolkit like http://asm.objectweb.org/ instead of straight bytecode  
manipulation.

2) Component management is handled by an open source IOC container  
instead of lookup routines from the Netbeans runtime.

3) Repository access is done through something like JDO instead of  
internal DBM-style management.  This one is a bit more complex, but  
JDO spec includes a flat-file backing store as well as SQL, and it  
should get MDR much closer to being runtime configurable for robust  
storage on SQL.

I also find that it's very important that the license it is  
distributed under allows binaries to be posted to locations such as  
the Maven repository at http://ibiblio.org/maven.  Having to log in,  
jump through hoops to download the latest, then extract the important  
jars from the results is an unnecessary barrier to entry and source  
of additional costs for users.

Other than those minor details, I'm ready to get started right away! :-)
