Hi Godmar,

You should talk Krzys Palacz (palacz@cs.purdue.edu), he has a cluster VM
implemented using JSR121 on top of MVM. I am sure that he has hit some
of the problems you are thinking about and most likely can help out.

Godmar> The second question is with regards to objects sent across Links, a

Godmar> Students of mine are thinking of doing a prototype distributed

Godmar> discussed as part of the API documentation.

Godmar> Thank you!
