And continued good success to the math arXiv project!
But why restrict efforts to centralized ones only? The whole point of
OAI interoperability is that it should no longer make any difference
whether a refereed paper is archived in a central archive or a
distributed archive or both! (The only alternative we want to avoid is
"neither"!)
By way of example of how it no longer makes any difference, CogPrints
<
http://cogprints.soton.ac.uk> is a centralized archive for
cognitive science -- but it is using EXACTLY the same OAI-compliant
Eprints architecture as is has been developed for distributed,
institution-based archiving by
http://www.eprints.org. In fact, the
OAI-compliant Eprints software was DERIVED from the prior centralized
CogPrints software!
And institutions are institutions, whether they mount centralized
archives or institutional archives.
And mirroring and harvesting for reliability and permanence are
available to both.
So why keep repeating that centralized archiving helped accelerate math
archiving more quickly than the prior (pre-OAI) distributed archiving?
True, but things didn't stop there. And linear growth is still linear
growth, whereas what we need is exponential growth, across all
disciplines, if we are to reach the optimal and inevitable before we
expire!
So let 1000 flowers bloom, central and distributed. Interoperability
will harvest them all.

Maybe that was because it was going it alone, instead of distributing
its efforts across disciplines, as the Open Archives Insitiative is
doing. It's one thing to adopt a standard, quite another to get others
to adopt it too.
(This is why your advocacy of centralized archiving and anti-advocacy
of distributed archiving is divisive and counterproductive: We should
be supporting every effort that gets all the refereed literature up
there, online, accessible, searchable, navigable, and free for all.
Centralized archiving has not managed this alone, so let it now benefit
from the help of Distributed Archiving!)

I don't understand this point. It may be another symptom of the
conflation between publishing and archiving, and between preprints and
postprints: What authors are choosing when they PUBLISH a paper, is a
journal, i.e., a quality-certifier with a known level of quality, a
trusted "brand." What authors are choosing when they ARCHIVE their
eprint -- whether the journal-certified, refereed POSTprint or the
unrefereed PREprint -- is a means of making their paper maximally
visible and accessible online, for free for all. OAI-interoperability
provides that, provided the metadata-protocol is shared by all
archives, irrespective of whether they are centralized or
institutional.
MPRESS apparently did not become such a universal (we might even call it
"distributed") standard. Perhaps this was in part because it did not
inititially adopt OAI's strategy of minimalism: Pick the minimal
functional metadata set, to maximize the ease of compliance, rather than
going all the way to Dublin Core from the outset. (OAI is inching
towards Dublin Core too, but thanks to minimalism and proselytising
across disciplines, it may manage to bring everyone else along with
it.)

I will have to leave this to OAI experts to reply to.

"Fragmented interoperability" is a tautology": The whole point of
interoperability is shared metadata standards unifying distributed
("fragmented") systems.
As to "hopes": The only pertinent hope is the freeing of the entire
refereed literature online. Centralized self-archiving alone (which I
backed for a number of years, initially advocating putting the whole
literature into arXiv) just is not progressing fast enough. Enter OAI
and distributed institution-based self-archiving to help speed it on
its way.
