o Why does he say that "best suited for static content; not suitable for
transaction environments" [page 13]? Did he elaborate on this statement?
Or maybe it wasn't LVS related ...

I believe he made this statement because he was laying the foundation for
the Convolo cluster solution which is (as I understand it) usually built as
a two-node cluster configuration where both boxes share one physical disk
array.
So both nodes have access to the data (though only one system at a time can
have write access) without using any IP traffic to synchronize.
I think this is probably what he was referring to.
They use their own version of Heartbeat to monitor a serial connection, a
network connection and a raw (shared) mounted disk device that each node can
use at boot time to decide if it should join the cluster and what resources
it should own and as a way of doing heartbeat-via-disk.
LVS could then help to load balance the Convolo boxes. Convolo would then be
a cluster within the LVS cluster I guess you could say...
Again, this is all second-hand, based on my understanding of his talk.
