An experiment has been conducted to implement Smalltalk and Java on top
of the Self development environment/VM.

See:
'Towards a Universal Implementation Substrate for Object-Oriented
Languages'

  http://www.sun.com/research/kanban/oopsla-vm-wkshp.pdf

Pulling Python and Objective-C into this equation shouldn't be too hard.

Porting Self to other platforms is a major undertaking though. (But I've
seen remarks that a port to Linux-on-Intel is under way).

more stuff on Self at Sun
  http://self.sunlabs.com
and at MerlinTec
  http://www.merlintec.com/e_technology.html

Javaites probably know that the Self VM project was where Sun's
'hotspot' technology was developed.

Cheers!
