I asked the primary developer to have a look at this, and he's managed 
to get the war files down to 145 MB, plus an additional 9 MB for the 
demo database.  The new release is here:


Obviously there are a bunch of jar files in there that are already 
shipped on OSGeo Live as part of other projects in tomcat, but I'm not 
sure it's kosher to try to store these centrally (I think the standard 
is to always package these up in the war file), though that could 
possibly save some more space.

As What If is a web-based tool that we host (and that's free to use) and 
that has been open-sourced relatively recently, it's not surprising that 
we don't have a long list of others who want to host a copy of it on 
their own webservers; they can just get a free account from us.

Sadly the development history didn't come along with the repository when 
it was open-sourced.

The install script is already done.
