I may have missed a capability. I'd ideally like each message
("session") to get a guaranteed-unique directory to work in, so multiple
instances could run concurrently. Something clever with Msgid?

No, nothing so fancy.  Just deliver the message into a directory rather
than a file, and procmail will determine a unique name for it (in much the
same way mktemp would) and store that name in the variable LASTFOLDER.

There are three possibilities:

# This stores the message in a uniquely-named file
# (see the MSGPREFIX variable)
:0c:
/tmp

# This stores the message in an MH-format uniquely-numbered file
:0c:
/tmp/.

# This stores the message in a DJB "maildir" format tree
# (expects subdirectories "new" and "current", etc.)
:0c:
/tmp/

Here's a fun feature I've never used:

 "When procmail is delivering to directories, you can specify multiple 
  directories  to  deliver  to  (procmail  will  do  so utilising
  hardlinks)."

I have _no_ idea what LASTFOLDER is set to, in that case.
