Agreed. It always looks more and more like we need a "generic transport
protocol" for flooding various bits of information through a domain. We seem
to consistently reject the idea, and then we consistently have ideas thrown
around about how to do this very same thing in some existing protocol...

Let's just add another AFI to BGP. :-)

Anyway, OSPF isn't the right place for this sort of thing.
