[rtcweb] Plan A, respun

[Adam Roach <[e-mail]>]

In order to facilitate discussion between the two SDP format 
alternatives we're considering, I've put together a document that more 
clearly spells out the Plan A approach as we originally envisioned it. 
Note that this is a slightly different approach than Cullen outlined in 
Orlando. I fear the Orlando approach may have suffered from its attempts 
to incorporate some elements of Plan B in an attempt to appease 
proponents of that approach; and, in doing so, lost some of its clean 
architecture.

The cleaned up, new-and-improved description of the Plan A approach is 
available here:

Note that we've omitted discussion of glare reduction from that 
document, as I believe that mid-session glare can be completely avoided 
by applications implementing a set of non-normative behaviors. These 
behaviors are described in the a separate companion document:

Thanks.
