Ah, very interesting. My understanding was closer to Mark's:

But, if I'm following your argument, that is actually a
_mis_understanding on my part. Very interesting.
Okay, if so, that is a nice separation, and David's usage is
correct, with POST-as-POST being reserved for RPC-style calls with
side-effects. I'll update the wiki accordingly:
The other issue with PUT vs. POST is that the error/return codes are
different, no? Does either plug-in currently handle those correctly?
