[Dovecot] Read-only mail folders

Is it possible to have folders on read-only partitions in Dovecot 
1.0-stable?

We have a NetApp fileserver which would probably be accessed via NFS 
(though iSCSI is possible) and which stores readonly "snapshots" of 
every directory accessible as .snapshot (but usually hidden from the 
operating system). It would be very nice to set up a "snapshot" 
namespace something like :-

namespace public {
  separator = /
  prefix = "#snapshot/"
  location = maildir:%h/Maildir/.snapshot/nightly.0
  hidden = yes
}

so that users could recover messages from say yesterday's version of 
their mailbox.

Unfortunately, Dovecot always seems to want to write to the directory, 
even when indexes are stored elsewhere (as recommended with NFS anyway, 
I think) using INDEX=whatever in the location line.

Best Wishes,
Chris
