Of tenuous relevance, but it's a cluster database which uses SCI for
signalling fabric.

MySQL 4.1 (just out) actually has cluster functionality built-in (but for Sun
Solaris, which is a release bug, about to be fixed). 

For those of you who're interested in HA Linux, the next release is not far
away, and removes the 2-node limitation: http://linuxha.trick.ca/

Dear Hugo,

Yes, I'm working on it. The latest code from Mikael works well with 
I built it with SCI yesterday and will test today.
I'll get back to you after verification of MySQL Cluster with SCI.

Thank you very much.
