Comet search engine -- free multicore Sequest?

Comet is the topic of this new paper from Jimmy Eng et. al., and it appears to be a search engine based on the original Sequest algorithm.  It has been adapted to be multi-threaded so that it can work on multicore PCs.  There are some caveats, however, to this (as well as most) free stuff.  The first is that there currently is no GUI (graphical user interface), you'll have to write one yourself.  The alternative is that you will have to order your searches using a command line (DOS, for us old guys) which will get very tiresome.  It also doesn't appear to be 64-bit compatible.  It is definitely nice that it is out there, but you will have to do a little work to get it where you want it.  I do like the icon.  It's blown up here because I couldn't find a higher resolution graphic, but it looks nice on a desktop.
