A fast OS X Xgrid using Linux and XP boxes as agents
http://jambot.com/blog/index.php?entry=entry070311-185623
This is a long looking entry but that's because of all the images :). It should take about a half hour to get your xgrid up and running.
Here's how:
First you need one Mac running Tiger (OSX) to control the grid. This doesn't need to be a powerhouse Mac as it will be acting as your controller, the only requirement is that the Mac is running OS X Tiger.
Have fun!]]>Off the beaten path but worth a search!

Gigablast
Operated by Matt Dwells this is probably the most sophisticated, advanced engine that could be in the "roll your own" family, pretty much a one man show but some major cool features and advanced options make gigablast a very cool and comprehensive search engine, I have a hard time believing you couldn't find what you are looking for there.
This engne is probably the most well known nutch powered search engine currently operating. Mozdex is in beta but who in search really isn't? Beyond promoting open source search, the operators are also looking for new ways to sell advertising to fund the expense of running a search engine, clearly they are thinking forward and also maintain a blog for further conversation.
Thats 2 for now! Check them out!]]>Search Engine Diversity?
