One thing I've noticed is that the "NoSQL" side of the debate (such as it is) always beats on MySQL as an example of a relational database. MySQL, for all its virtues, is like the little kid brother of real RDBMS systems. Getting slightly improved performance opposed to a NoSQL system is NOT going to convince someone with a behemoth Oracle rack to switch. I'd like to see some systems and benchmarks showing how NoSQL systems can compete in the ridiculously high-volume, high-speed space. And yes, I know Google does with BigTable, and that it's theoretically possible, but I haven't seen any implementations prove they can, yet.
