#4Is this one of those, "If you have to ask how much it costs, you can't afford it?" situations? Because "Try it now Free!" is the only thing I can see on their site related to a cost, and "First one's free!" rarely means it will always be free. :|

there are a lot of new features! Beyond distributing data across multiple machines in a cluster, there's more SQL surface area, multiple levels of redundancy for HA, and a distributed query optimizer. Some cool stuff with bi-directional lock-free skiplists too w.r.t. indexes

Their resource estimator starts off at 1640 cores [1] and even the bottom most tick on the scale represents 500 cores. For people who can dedicate that amount of hardware to their database the licensing cost is probably not a major component.
The numbers look impressive, though.

#7the problem with scaling out to multi cores with a focus on ram is that in larger datasets you end up trading disk latency for network and protocol latency. I a not sure that is a great trade even if we are talking about fiber channel as a medium.

#8Great design on the site! Congrats to the memsql team

I have to disagree; disk is ancient - it's mechanical egads! - while 10GigE is pretty commonplace now and infiniband and fiber channel are even faster.
back from my CS 101 takeaways: there are only 3 bottlenecks in a computer system: CPU, network, and IO.
looks like MemSQL is fixing the CPU and IO bottlenecks, but physics is physics so network is pure hardware solution haha

#10How does this compare to kdb+? This seems like a much less arcane competitor.
