At least you'd want your publication to look up views like the 
HTTPPublication, yes.

You probably want to implement your own publication that works on 
browser requests but immitates the HTTPPublication behaviour (though 
probably only in some cases, I assume). Custom publication/request 
factories can be registered with the 'publisher' ZCML directive:

       methods="GET POST"

Factories with higher priorities will be called first. They can decide 
whether they want to handle a request based on the (CGI) environment of 
the request. If they decide not to handle, the next factory takes over. 
The fallback is the browser factory, then the HTTP factory. See
