Yes, both approaches (singlethreaded ROT-Singletons with direct access to
the worker-class and ROT-Dispatchers with indirekt access to multithreaded
worker-pools).
But always behind our own (socketbased) Appserver-Environment and not in
combination with COM+.

It works well, but you have to ensure a very clean timing/timeout-handling
(over the entire roundtrip) - especially, if you want to use the
singlethreaded approach - so that the ROT-Objects are never blocked for more
than 1-3 seconds.
