That's the first thing I tried but it isn't as easy as it sounds.  The 
client and nations use the same numbering system for nation ID's, but 
both assume (in find_nation_by_name, for instance) that the nation array 
isn't sparse.  So either the server would have to delete the extra 
nations internall, or the client would have to be able to deal with 
knowing that there are 76 (or whatever) nations but only having data for 
16 of them.

Also I think it isn't robust.  It depends on things happening in exactly 
the right order.
