I agree with your comments that toolbars should respect the robots.txt because even if a human is doing the crawling, it is still an automated system that is indexing information from that site. I would not want toolbars attempting to send data back to Bing based on my queries on a company Intranet or a site that would normally not be indexed. Personal data entered into what the toolbar thought was a query field could be sent onward as well even if the robots.txt on the site restricted it. I think they should respect robots.txt in this case even if they are only monitoring user behavior.
