If FS just did signaling forwarding the majority of the functionality would
be in the html5 side.  At that point it would just be copying what Jitsi
can already do.  With the limited time (by time I am talking about the rest
of the 2000's) we have to focus on things that add new relevance.  It would
be kind of like adding sip proxy features despite the existence of 2 major
SIP Proxy Implementations.

There is an endless flow, like the tide of the ocean, back and forth
between putting work on the client vs the server side.  Like Jerris said,
mobile devices (even some small laptops) nearly overheat with 4 or 5 video
streams up and also those video streams are all low resolution to
compensate.  I don't say one or the other is better, its all science.  My
ClueCon presentation last year was all about this.
