I don't have any experience with changing a running program other than changing variables.  If you want to reload
the non-volatile memory with new code while you run then your while loop on the slave nodes sounds fine.  You
would do everything on the master node, and still that would involve asking the slave
about volatile settings, (which would be in flags it set), and handling checking for inconsistencies caused by
reloading the code as you run.

PS "scripting inside an MCU" does sound like forth to me.  Or maybe LUA.  Don't know.

John
no forth experience yet...
