I really like the format and layout of your engine list, its very nicely done. I see it is powered by DMEngine V2.
Is DMEngine V2 a COTS product or is it something that you have developed in-house. If so - have you any plans to release it to the public domain?
I have been toying with an idea to produce a "list" very similar in functionality to yours, but listing a completely different set of products.
Either way - well done - the best engine list on the internet....
