Er... Yes, that's it. I can't even understand what Morgan means. A results cache must not be such a bad idea if many major DBMS implement it in recent versions, including Oracle itself.

However, the database server runs 10g. If I tell the customer that in order to run an auxiliary web reports application they need to buy a licence for 11g, upgrade their server, check that all existing apps (functions, stored procedures, ERP, several custom Oracle Forms utilities, online orders web site, backup system...) do not break... I'd say they won't be amused.
So I assume the only way to obtaining table names is explain plan :-? I guess I'll stick to my PHP-side solution by now.
