[CentOS] Memcached - replication?

Hi all.

I am thinking about installing memcached with replication, I've found
http://sourceforge.net/projects/repcached/files/repcached/2.2.1-1.2.8/ but
it is for 1.2.8, and for Centos 6.3 memcached is in version 1.4.4. I do not
want to use client side "replication" (writing to two memcached nodes at
the same time) and haven't found other solution.
Are there any good, protocol compatible solutions? What do you think about
couchbase?

Best regards,
Rafal.
