Thanks for the pointer. That's an interesting document. I've read it
once but need to digest it a bit further.

The crux of the issue, and what I was getting at in this thread is
what you refer to towards the end:

"It is possible that D2 and S2 can be used side by side by different
communities for quite a while before a collision of the sort described
above becomes a serious interoperability problem. On the other hand,
when the conflict does happen, it will be very painful."

I think what I'm interested in is what problems might surface and
approaches for mitigating them. I'm particularly curious whether
heuristics might be used to disambiguate or remove conflict.

Yes. That's the only piece of software I've heard of that has problems.
