[jboss-user] [JBoss Messaging] - MySQL in Cluster question

We're using JBoss 5.0.0.GA with it's JBM and want to use a MySQL cluster as the underlying DataSource.
Currently we're using MySQL 5.0.51 - so the cluster is in-memory.
What will the maximum message size that we can send. I've seen a note on the MySQL site that mentions that there's an 8K limitation on a table row in the cluster. So, question is that the JBM_MSG table stores the headers and payload as blobs and we could be sending TextMessages of 10k characters or more. Would this be a problem?
I'm a bit puzzled as I've managed to send a 10k message through the cluster - but I'm worried whether I'm missing anything.
I have had a bit of a trawl through the forums but couldn't see anything that quite fitted the bill.
As a follow-on question what would be the effect if we could upgrade either to MySQL 5.1.x or possibly to MySQL NDB Cluster 6.x?
Any help would be appreciated.
