And indeed for several years: my own 1995 work at ESA offering a
query interface to order satellite data remains unchanged today.
Manipulating geographic data was probably also the first application in
which we saw a range of sensible applications of JAVA on the client side.

I have to disagree with this.  Even if we can rely on browsers supporting
