I don't yet understand why exmerge would come up in the context of PST
files:

  * to achieve the stated goal of exmerge, OC offers 
    openchangemapidump and openchangemapirestore. They take mailboxes
    from server X and put them on server Y. The only thing lacking is a
    merge feature, but I can see that is important and should be
    included. And while exmerge uses PST as an intermediate form,
    mapidump uses a format you can manipulate with LDAP and SQL
    commands.

  * the reason (I suppose) PST file merging with Exchange inboxes is
    for migrating on and off an Exchange server. However exmerge
    doesn't seem to be able to do this. From the description it seems
    only to be able to do server <-> server, although presumably you can
    trick a two-stage merge by replacing the PST file at the right 
    moment.

So, if we can make sure that openchangemapidump/restore together are a
functional superset of exmerge, which they certainly should be, do you
see any extra value in exmerge with respect to PST files?

What I was proposing someone other than OpenChange wrote was an
Outlook-specific tool that will either pull down to PST or upload to
Exchange.

Have I missed something here?
