First, be careful if you want change bbox in getCapabilities with the
org.geoserver.security.DataAccessManager, multithreading cause some
trouble (I was wrong in my mail :)

It's depend on what you want. If it's just blocking request which are
not in a certain boundingbox for a certain user, it's very easy thanks
acegi,spring and the org.geoserver.ows.security.OperationInterceptor (if you
want know how it's works, you can read org.geoserver.ows.Dispatcher#execute
in ows module).
Nevertheless, if you want rewrite response (for example having picture with
information only in the permitted Bbox), it's harder, you have to rewrite a
part of response's writer (perhaps another solution exist but I haven't
found it :()
>It might be interesting to get that code, review it and commit it.
I'm sorry, but I'm speaking with my manager in order to know what part of
the geoRm I wrote can be opened ...
