Qlikview's options for getting data out suck royally. Your basically forced to use their native Windows client. Their web stuff is too immature to be viable.
This is distributed though, which I think makes it quite interesting.
Doesn't make it interesting for me; OLAP queries are very easy to distribute.
Also, kdb+ achieves a "billion rows per second" scan on a similar dataset with just one or two instances (rather than 40), if you know what you are doing.
