Perhaps I have my marketing hat on but the point of a logo has always been, to me, that it clearly demonstrates at a glance what the item is; the toolserver logo ( http://commons.wikimedia.org/wiki/Image:Wikimedia_Community_Logo-Toolserver.svg ) is a great example of this. What about having half the center be the ship and half a magnifying glass (classic symbol for a search), or something of the sort?

Something like this, but fixed up and less crappy (this was a sketchy sort of see-how-it-looks image). I'm sure it could also be done like the toolserver logo and have half a ship and half a magnifying glass... or perhaps a magnifying glass larger with the whole ship inside?
