I may well be maligning you but on the other hand I have over 20 years experience working as a trader/researcher and developer in the finance industry for tier1 investment banks as well as hedge funds and have seen a lot. You are not doing this for "the greater good" you are doing this to make money, as is GETCO et al. Stealing algorithms and protection of algorithms are fundamental issues in the industry.

I would suggest you guys try to assuage fears about this by doing as much as possible to prove your true intentions.
