I've used the embedding API to some extent, but I'm not sure about 
"multiple toplevels".  It's unclear what "toplevel" environment(s) 
you're referring to.  There's the C_toplevel and I'm pretty sure 
there's only one of those.  The Scheme toplevel runs after 
CHICKEN_run() is called, and can be stopped and resumed (by 
return-to-host and CHICKEN_continue), but that doesn't say anything 
about multiple, simultaneous, independent Scheme instances.  

Maybe that's not what you're driving at.  What kind of "interaction" 

do you mean, and what would it achieve?  I'm thinking it could be 
difficult to get there directly, but perhaps there are other ways to 
accomplish your goals.  More info about what you have in mind would 
probably be helpful.
