Infovell - the new library research tool du jour?

Has anyone tried Infovell, a deep web research search engine that has gotten a lot of play in the media (like on ReadWriteWeb in September).  You have to download it for a free trial to check it out, so I'm guessing that most of my lazy net friends haven't done that ;)  It would seem to be a hugely important tool for libraries to try. 

I've been monkeying with it for a bit, and am impressed at how many different information sources it's pounding on.  The interface is quite usable too - nothing to complain about (which is a shock coming from me, I know). 

Does this have an application in libraries, even though they are primarily marketing to companies?  Should libraries purchase this tool to help us help our users with their research?  Particularly academic libraries?
