panoptech.com - search tool that sat in your system tray watching keyboard input and doing background searches so that it would have results immediately ready for you anytime you wanted them. circa 1999, no one cared about privacy issues back then :) feedcache.com/feedcache.net - QOS for RSS. Idea was to cache every RSS feed and their associated enclosures, etc. and make them available via API so that application developers had certainty that they could retrieve the content from the feed when they needed it. circa 2003/2004ish. Internet infrastructure sorta caught up to the idea pretty quickly and we also realized that it was too hard to compete by just providing QOS on content that a) didn't belong to us and b) was freely (usually) elsewhere. I literally have hundreds of others, and these two are my favorites...
