Looks like they tracked it to a steam update in March, and there's a workaround for at lest 3 games that involves all players copying steamwebrtc.dll to the game's ./binaries folder.
It's just something so heartwarming of multiple people coming together to describe their symptoms, workarounds and theories of what could be causing it.
Granted, I expect a lot more out of Valve than the MS-culture/folks that led to 343i / Halo Studios (since from every single bit of evidence, the cultural problems continue).
Maybe they need a few average devs there to spend time sweeping up behind the paragons that are pushing the envelope into these features existing at all.
