same experience here: nothing should prevent you from holding those 
different states over at the server (at least not at the layer of the 
WebContinuations: I haven't waded deep enough into the js implementation 
to understand all usage of the session that could block this)

So if I understand correctly you would have different portions of the 
screen filled in by different widgets that each introduce their own set 
of URI's holding their particular continuation ID?

of course this more ties the portlet to the continuation id then a 
flow-script (or Apple for that matter) which feels odd to me since I 
keep seeing a portlet as a widget/screen (thus view) component and a 
flowscipt as a controller

Hm, I guess this goes along with how you are conceiving Dywel? For all 
we've talked about it I sensed the same tendency to somewhat treat 
controllers and views as being one and the same..

The distinction is probably only in my head, and surely the way web 
encodes everything over one URI + set of request parameters adds 
argumentation to your view...

So while it's not my natural view, I'm quite interested where all of 
this is bringing you, sounds like something could be learned here.
