I'm currently updating my proposal, trying to incorporate the points
people brought up in this thread.

I realized that trying to use the same kind of "read only mode" for
both a standalone postgres (with the datadir on read-only storage),
and a PITR-slave was missguided - 
http://archives.postgresql.org/pgsql-hackers/2005-11/msg01043.php
was really enlightning ;-)

Tom's objects regarding performance are the hardest one to deal with -
I'm currently thinking about ways that the locking requirements could
be relaxed - though I still plan to do a basic implementation first, and 
then try to improve it.

I'll post an updated proposal during the next few days.
