Basically it is just a RabbitMQ cluster running on 8 x NSLU2 devices,
I think 3 of which are running as disk nodes and 5 as RAM nodes.

This is the circulum vitae of each node:

* 100baseT ethernet port
* 2 USB 2.0 ports
* 133Mhz ARM9
* 32Mb RAM

Each SLUG is running the ARM port of etch.

It's as not as special as it sounds - we mainly use it as a cost
effective way to test clustering (being a pennyless open source
outfit). And for demonstration purposes - you can take it with you to
demonstrate clustering at a talk, for example. And also to show that
you can run Rabbit on resource constained hardware.

The set up is just plain jane OTP clustering - see here for details:

HTH,

Ben
