I see they haven't updated their sales process - you have to fill out a form (to be tossed into their funnel) to download.

Licensed on memory capacity of the leaf nodes. Roughly $8k/year each which is inline with most other commercial databases.

4-node (up to 32gb RAM each) cluster is free to use though with all features.
