I came across http://dopiaza.org/flickr/flickr-set-manager/ while perusing some contacts photos on my Flickr account. This Web App is the brainchild of Brian Wilkinson . Another IT guy and avid Photographer. As the FAQ page goes on to state:
“The App basically just uses the Flickr API to search for photos on Flickr that match the conditions you enter. It then creates a set on Flickr containing these photos.”
Its really easy to set up and it takes only a day at the worst for your new set to show up. I kind of like it. Check out http://dopiaza.org/flickr/flickr-set-manager/ and let me know if you are using it!
For more information check out the Set Manager Flickr group to ask more specific questions. http://www.flickr.com/groups/setmgr/
