[PLUG] 3-way data mirror?

I have a situation where I have 2 labs that need to keep ~150G of data in sync, but they can't talk to each other. They can talk to a 3rd machine, which is also backed up, so...

What I think I'd like to do is have:

	Lab1 <--> COLO <--> Lab2

The problem is that lab1 and lab2 are both read-write, so there is a real possibility of stepping on changes. COLO is read-only.

I'd try to just relay through the COLO, but that's also where the backup will happen. And I can't get the FW rules changed.

Any better ideas?

Any suggestions on tools? I'd strongly prefer something already in the CentOS-5 or EPEL repos.
