Anyone running a free app want to try a in-ram MySQL NDB server on me?  
RobGR: I am very interested in your project and I hope you publish your results.  I don't have a suitable database project, unfortunately.I have been experimenting with master-slave replication in MySQL.  I am interested in performance, but redundancy and high availability are more important to me.I have a question -- if you are doing high end RAM based MySQL servers, won't running them in a virtual machine introduce other issues ?  Shouldn't these be standalone real computers ?
