Sorry to be such a bother with all these posts, but to answer my own
question (after a bit more research), the data would actually go into an
NSMutableURLRequest object via a setHTTPBody: message, with the HTTP
headers and method set accordingly.

After poring over the CUPS source until my head hurt, it appears that
the answer to this question is "yes".
Well, sort-of. You can use the ippReadCB and ippWriteCB methods to
read from/write to a memory buffer. You can't just cast to ipp_t *
and go... :)
Ultimately, it would probably be easier to tie into the keychain
API from a CUPS password callback...
