Do we need a set of requirements for each object?  For example:

- hardware floating support prefered
- sound capability essential
- indication of memory useage
- with what other objects will commnuication be most frequent - this is 
  to help prevent closely connected objects from being migrated to far 
  from each other.

One solution to the last problem is that one criterion for the migration 
algorithm should be to keep the messaging path between closely 
interlinked objects to a minimum - ie to have a minimum cost spanning 
tree for the communication paths between an object and all it's
