Looks like it's a very thin wrapper around scapy: http://www.secdev.org/projects/scapy/

Here are Felix ("fefe") von Leitner's comments http://translate.google.com/translate?js=n&sl=de&tl=en&u=htt... Not that I would share his views, but he is a relatively well known German security expert and free software activist (dietlibc). He knows GnuPG pretty well and basically says: Werner, you don't deserve our donations, stop crying, get a day job and maintain GnuPG in your spare time.

1) The component used for the web interface is not part of the demo

2) Check out hyperdemo/scripts/tpch/load.sql, HyPer uses the same syntax as Postgres, i.e. you run bin/sql, create a customer table and load it with

  copy customer from '../tpch/customer.csv' delimiter ',';

3) Please contact us http://www.hyper-db.com/#team

If you're interested in query compilation, check out the HyPer DBMS prototype at [1]. It efficiently compiles SQL (SQL92++) to super-fast LLVM code (faster than Vitesse). It's not open source, but you can download a binary [4] or try it out online using the "WebInterface" link and read about the query compiler here [2]. It also has lots of other goodies, like SIMD-powered CSV parsing (about 4x faster than Postgres) [3]. Rumor has it that the prototype will be commercialized soon ;)

EDIT: It also has NUMA-aware multi-threaded query execution.
