Ok, well I'll try this out for performance. I'm curious to see what I'd be
able to handle doing live mysql routing decisions with all the new prepared
statements and such.
Of course, I'm a big proponent of doing memory routing, but I may need some
capabilities to route based on other factors such as ASR and PDD to
automatically set the route priorities. Maybe a module someday.. :D
