Krugle: search engine for developers

Hey you developers,

Krugle Inc., software company based in California is developing a "vertical search engine" specialized in code search.
On their web site you can find a demo: it is quite difficult understand the product’s potentialities but the UI interface is attractive, it looks like an IDE giving the possibility to browse the results as if they were projects located on your workstation.
The beta subscription program is over so we have to wait to try it.
