Mick - it's a good idea, but would takje a very serious effort to make it work, and a lot of cooperation. BUt I could see a master serach engine hitting all the locations with a very powerful advanced search technique ... then cooperation among the sites around rules for upkeeping data, and cooperations about specialties and display formats ... could be a wondeful rich resource. But Mudcat and the few others I use are already pretty good!
