Then the BlueQuartz list will probably be more appropriate for you... 
this is the BlueOnyx list.  Similar, but not quite the same...

But now, regarding your clustering...

Aventurin{e}.  http://www.aventurin.net

You set up Aventurin{e} on both servers, which then runs your BlueOnyx 
(or BlueQuartz, or...) as a VPS.  Aventurin{e} then clusters the 2 
servers and keeps one of them in hot-standby as you have described.

You cannot really set up 2 standard stand-alone BlueOnyx (or BlueQuartz) 
servers and mirror them, since the CODB data will not sync up.  They're 
just not built to do that.

Aventurin{e} addresses that by essentially mirroring the same BlueOnyx 
(or BlueQuartz) server across 2 different physical pieces of hardware. 
If the "primary" falls down for whatever reason, the "secondary" will 
take over.

It comes with a GUI and everything.  The software isn't free, but 
speaking as somebody who's seen it in action, it's well worth it.
