Define a minor mode that binds that key and only activate it in the
buffer you want it in.

I don't see why that wouldn't be elegant. IMHO it's more elegant than
defining a special minor mode for the sole purpose of being able to
return to the correct base buffer.

BTW, are you aware of the function `buffer-base-buffer'? It tells you
what the base buffer of an indirect buffer is. No need to mess with
buffer-local key bindings or buffer names or what have you... :-)
