[plt-scheme] Using DrScheme as editor for an external Scheme system

This is definitely doable. As a matter of fact, DrScheme started that  
way. For the first year, we had the option of running Chez Scheme or  
PLT Scheme as the REPL language. But this is ancient history and I  
doubt that any of the code from back then still exists.

In the meantime, the Brown crew has embedded OCAML in this style and  
Dracula does communicate with the ACL2 theorem prover in this manner.  
(The language semantics, however, is implemented via macros and PLT  
Scheme.) I suspect that Dracula is a better model for a starting  
point but I am not sure.
