Exhibit can't do #2 because it only acts on the page at runtime, so the 
author of an exhibit must put that in herself. And that I just did for 
the ESWC 2008 exhibits.

BTW, Semtech 2008 has a cool Exhibit-backed event browser:
Maybe future *SWC conferences would have use for the same service.

So, it'd be good to get lat/lng coordinates for the affiliations and 
then plot the speakers on a map, like what I did for ISWC 2007 (just for 
Now, with all that open linked data, how much work does it take to get 
lat/lng of 2 dozen well-known organizations? Should be trivial, right?
