Interactive Bookmarks

[Derek Belrose]

I'm wondering if someone has already come up with a patch for this:

What I want to do is something along the lines of a bookmark that when clicked 
opens up a dialog box, and accepts input, appending it to the query of the 
URL.

For example:  

www.whois.sc will take a domain as a query argument, so:

http://www.whois.sc/kde.org will bring up a page with the whois info for 
kde.org.

Is there functionality built into Konqueror for this?  Or how would I go about 
implementing this functionality
