Either alternative SMALL or LARGE is reasonable, but I don't think that
MEDIUM is viable because ENVIRONMENT-REMOTE-P and
WITH-REMOTE-ENVIRONMENT aren't very useful if you don't have
ENVIRONMENT-PROPERTY. ENVIRONMENT-REMOTE-P might be useful in
conjunction with FIND-CLASS, but the use of environments by FIND-CLASS
seems to be in question now.

Need to make clear that this affects the global environment, not just
all local environments.

"same model" is not a defined term; would be more precise to say all
environments which inherit from the same remote environment.

Yes, I think that would be a good idea. For cross-compilation, I would
want the COMPILE-FILE remote environment to inherit from a remote
environment representing the target machine. How about a :PARENT option
for specifying a parent environment?
