It says on their website:
"JetBot is JetEye's Web crawler. Our robot identifies, retrieves and stores Web documents to build a searchable index for the JetEye search engine. "
I guess maybe when it has crawled enough they will actually launch the front end of the search engine?
It has a FAQ section here:
http://www.jeteye.com/jetbot.html but it mainly talks about robots.txt and how to stop it crawling some or all of your site.
