replication between datacenters

[William Francis]

We currently have mogilefs running quite satisfactorily for our service 
and we're growing into a second datacenter initially for disaster 
recovery but eventually load balancing as well.  After a couple hours of 
searching and looking through CPAN I've noticed that it seems to be 
something that has been discussed several times in the past (here and 
elsewhere) but I've been unable to locate anything that suggests the 
best approach to take for our situation.  Did I miss something or is 
this still in the realm of 'gee that'd be neat' but there's no generally 
accepted way to do it and it's just been hacked together somehow each 
time by people who need to solve this problem?

Any pointers greatly appreciated and thanks for something that works 
beautifully!

Will
