The only thing I can think of now is to subclass PagedLOD and try to

Subclassing PagedLOD will be very difficult, I expect. I think most of DatabasePager is
only aware of the parent PagedLOD class. I think the only way to do this would be to
extend the base PagedLOD class to have additional virtual-method hooks that can be
overridden in a derived class or as callbacks on particular instance.
It sounds like your design would have all your PagedLOD instances behaving
consistently, so configuring things to support this behaviour in a derived class is
probably the way to do it.
I can advise a little on this, but I'm in a non-OSG development phase right now, and my
OSG tree is not at all current to CVS and I'm not checking the list very often.
