>Can anyone describe to me why when you call SetAbort() or SetComplete(), the proxy stub effectively disconnects you from the server instance and fires up a new one on the next call and yet it can't pool those instances? Why does it have to shut down and re-start instead? The client would not know the difference, it's a matter of the server shutting down and re-starting instead of taking form and returning to a pool... Right?

This is resolved in COM+. You can commit or rollback the transaction without disconnecting from the component.
