Another kind of answer would be an algebraic expression to be compared
with another expression. It can't be compared by using textual matching,
even regular expressions. It does need a symbolic evaluator able demonstrate
equivalences.

For 2D objects, a module communicating with DrGeo would be sufficient.
Would Hilaire Fernandes like to develop a communication protocol for
DrGeo ?

the gateway for the local network can do some parsing of the URL's, or
it can restrict the access to a local mirror.
