Another approach is to design out the source of the problems you mention, by never ever using dynamic binding for things that static binding solves better (See my rant on this very topic at Gamelon/Earthweb, Nov 2001).
See http://virtualschool.edu/jwaa (Java Web Application Architecture) for an open source solution based on the above. In particular, note using static type-checking for reporting invalid links, and the use of centrally-mained Field libraries for getting input validation under control.
Finally, use junit for unit and integration testing.
The rights management demonstration at http://virtualschool.edu/mybank can aderess many if not most of the concerns expressed on this list, once commcerically deployed and stocked with content of higher quality than is generally available for free. I'd welcome any/all comments on the approach described there.
To head off a misunderstanding already expressed here, flat rate pricing is trivially available via this system. Pricing is set by the content owner, and flat rate pricing is one of many pricing options available to them.
