dynamic mixin

                 Key: ETCH-61
             Project: Etch
          Issue Type: Improvement
          Components: csharp-binding, java-binding
            Reporter: scott comer

there are times when a statically constructed mixin isn't quite enough. if you consider an
etch gateway or router, then the decision of which etch services need to be accessed on a
given connection needs to be made after the connection is established. another form of this
is filters which are added at runtime (yes, right now before the connection is established,
but perhaps not in the future).

an example of this is a generic gateway between soap and etch. the gateway has a repertoire
of say a dozen or more etch services, but it doesn't know which one you want until you actually
connect and tell it. so initially you have a simple etch interface you're using, login, etc.
then you send a request for some service. the gateway realizes it doesn't yet have that service
in your mix, finds it, determines that you can access it and makes the connection, then dynamically
mixes it in.
