Whether they register for event types is orthogonal to whether the data 
channel is a web service. An app registers for event types because it is 
interested in receiving those (and only those) events

This is meant to be a general solution. What if I don't want a data 
channel? What if I want two data channels in order to make my application 
logic clearer?

The venue client's public id? what if I create an app that stands alone and 
isn't part of a client? What if I create two instances of an app associated 
with one client?

I don't follow; how does an application get created if there's not a 
factory to create them?

What if I wnat to derive a custom application class that has server-side 
code in it, and create an application server, all using this same 
framework? The app factory is a general mechanism..
