Did you know that Rackspace has a cloud offering? I didn't. The name is Mosso.
Someone from Rackspace/Mosso on the drizzle-discuss mailing list offered to hire a person full time to work on Drizzle. Curious? Find the post on the mailing list.
Drizzle has a lot of potential for making it easier to run a DBMS server on the cloud. There are a few things that need to be done differently from traditional MySQL replication. Drizzle has started over and has removed the code inherited from MySQL. Their focus is a clean API (right Jay). There should be a lot of interesting work that can be done.
