I'm interested in in implementation of the asset services, even 
completely fake, with mainly login like the simulators now. This is 
something just to give backbone to the current documents combined with 
implementations since then without any specific group behind the 
backbone. It doesn't have to support real simulator details, it could 
just forward proxy if it really want to turn into something. That's just 
the scrape for implementation sake. We need something like this, yet to 
justify it beyond people's agendas is... not productive.

I mainly wanted asset services unitized in order to support the 
multi-point/multi-client perspective, yet, like last year, I'm tired of 
being harassed by... agendas. We could always fallback to the proxy 
being on the viewer-side. *sigh*

On the documentation side, I think we could take the current proposed 
RFCs and simplify the type system into split documents instead one (that 
mainly reflects the monolithic design). That way we could come back 
later and easily update the more simplified versions. Just my 2 cents on 
the current state of them...
