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?
