scrypt is no cipher, it's a key derivation function based on a hash. see [1] or [2] for details.
I know that http://www.ovirt.org/Features/AAA_JDBC states there will be additional anti brute force mechanics, but those don't apply e.g. if a database gets stolen.
We relay on what Java JCE can provide natively to avoid US export regulations issues. I believe that the basic implementation of random + hash(random, password) should be sufficient for 99% of cases. If someone needs additional security he can always fork this extension and enhance it or just use LDAP which complies with the requirements he may have.

Why do you need cipher when you can use hash?
PS: This is just a general remark regarding security.
I don't know about the scope of this feature as it is neither stated in the BZ nor on the wiki, so I might be wrong.
