[ much good stuff snipped ]
| Of course, one way to avoid the thornier issues is to consider each
| be running on its own virtual VM, with the UVM being more of a VM factory
| an actual VM. Then, normal IPC (COM, CORBA, whatever) can take care of
| semantics among virtual VMs, and we can ignore questions like "how do I
| multiple values to a BASIC caller?"
One possible solution that has been discussed (don't remember who brought
up first) is making VMs first class objects in the LispOS - which I believe
a far better solution than trying to create a true UVM (not that it
represent the Holy Grail of VM-dom). The portable LispVM could be specified
with this also - a meta level system capability independent of any
language's VM definition. This might be considered a meta-VM (MVM?) - the
specification of the environment the language specific VMs will be embedded
including the inter-object communication layer(s).
