IBM_Planetwide: apears to be a spider from the IBM clever project.

Ia_archiver: Alexa.com and/or archive.org A lot of people ban this one because it is very badly behaved.

Wisenutbot: Wisenut search engine wisenut.com (part of looksmart)

The World Wide Web Worm: Have never seen it but belive it is something to do with Colorado university (posibly a project, or research bot)

Hope this is of some help.
