Odd/Even Autoincrements

Revisiting the issue of high availability.

I know that you can have dual masters; each replication each other. You
just have to make sure that with your primary keys there aren't any
conflicts.

With two masters and systems that utilize an autoincrement for their
primary key, if you could ensure that one system autoincrements only even
numbers, and the other system with odd numbers, if either one ever went
down, when the system came back up, they should be able to resync without
any conflicts.

Does anyone utilize something like this above?
