I've been working on an open source implementation.  It consists largely of
re-purposed code pulled from my open source DKIM stuff.  There's some final
plumbing I need to connect before it will be releasable.  I think the ARC
protocol, since it borrows so heavily from DKIM concepts, actually ends up
being less complex than it appears on paper.

There's at least one issue about the document that needs addressing, which
I believe has been raised already in some other context: The prefixing of
an instance number to the ARC-Authentication-Results field being described
only in prose leaves the proper syntax ambiguously defined.

More generally, I think the document needs quite a bit of polish.  The core
material seems to be there but I've got some qualms with its organization,
flow, etc.  This may also be contributing to a false veneer of complexity.
When I'm done the first round of coding, I'll route some energy toward
development of the document with the authors if they're amenable.
