Yeah, the idea hadn't quite fully formed in my head yet.  It's really
"property" but that's too overloaded.  I think people will guess what
"parameter" meann pretty accurately.

Right.  Mainly, you could set/get one via messages (via an event port)

dynamically.  I like that this is tied in with ports so the abstract
concept of a "parameter" is not tied to the logistics of ports or
whatever else.
