Ok, let's scrape all the information together and try to get
a picture. :-) That's what I have:

* mmap: All overview methods use mmap (regarding one of Heath'
  older mails, <200007131941.OAA00745 at>).

* Locking: All overview methods use fcntl file locking.

* Heath also mentioned
  for ovdb (-> Berkeley DB and remote file systems).

What about the rest and mmap / locking? Spool (as I mentioned,
we'd like to use timecaf), active, history etc.? 

We are big fans of NFS storage solutions (NetApp, EMC²), but if
this will not work: What are others using? Two people suggested
Compaq storage solutions, anything else?
