Ils sont d’ailleurs en train de préparer des offres dans ce sens :

Je les ai questionné à ce sujet et voici leurs réponses :

Hi there!

You’re receiving this message because you’ve specifically asked DreamHost
to contact you when we’ve resumed sales of our dedicated servers.
Well…that day has come!

We’ve done some soul searching in the past few weeks and we’ve realized
something. Shared hosting is our bread and butter. The varied hardware
configurations and somewhat custom software environments required by
dedicated servers really don’t mesh well with our streamlined,
well-oiled, centralized management systems. Providing support for
dedicated servers in the past really took up a lot of our time – from an
inventory, administrative, and technical standpoint.

So! We’re going to try something a little different. We’re going to
give you all the features of our Strictly Business hosting plan (see
http://www.dreamhost.com/shared/comparison.html for the full scoop) but
you’ll be hosted on your OWN server. You’ll be hosted on the same
standard hardware that hosts several *hundred* other domains in our usual
shared hosting environment – however you’ll be the ONLY customer on it.
The entire CPU resources of this single machine will be devoted to
serving up your sites and your sites alone. We’ve never done anything
like this before and we hope you’ll be as excited about it as we are!

Currently these machines contain 2.4Ghz dual-core AMD Opterons with 4GB
of RAM. Hardware upgrades of any kind will not be available. If your
server experiences a hardware failure in the future we *may* move you off
to a different server, however you will always be moved to whatever
standard platform we happen to be using at the time for our shared
hosting customers. That future server configuration may vary from the
one quoted above.

These servers will be fully managed, just like our shared hosting
offerings, and they will include the world-famous DreamHost web-based
account control panel. Root access will not be available. MySQL
databases will still be hosted on our shared database servers. We will
monitor and provide support for your server at no extra charge, just as
we do for our shared hosting customers. For all intents and purposes,
you will interact with your account just as if you were a shared hosting
customer

The cost for this new "Strictly Business – Enhanced!" package is $400 per
month. Payments must be made on a monthly basis, and there is no setup
fee. If you’re interested in taking advantage of this offer we’re taking
orders now and we would expect to have you set up no later than the end
of August.

Don’t bother looking on our website for more information – you won’t find
it! For the time being this is an exclusive e-mail-only offer being sent
to people like you who have asked to be notified when something more
powerful than shared hosting would be available from DreamHost.

If you would like to place an order for "Strictly Business – Enhanced!",
just reply back to this email and we’ll be happy to get you all set up.
We realize that our "one size fits all" approach may not be a good fit
for everyone, and for those people we can only say that our partnership
with Hosting.com is ongoing. For more information on that, be sure to
check out http://www.dreamhost.com/dedicated/

Please note also that this is the first and last email you will receive
from us regarding dedicated server availability. As of now, we’re
vaporizing our waiting list. It’s gone! Finito! Bye bye!
