I don't remember all the details anymore but sharing IP address for numbered ptp I/Fs is not pathological.
Having two independent networks with the same IP prefix seems pretty pathological to me.
No, it works fine when you don't have real unnumbered. The only difference in the extra entry in the router LSA for numbered PtP links. In any case, if someone does it should just work. I don't recall OSPF says it should not work.
It should just work. Also any combination of numbered vs. unnumbered, IP address or no IP address(even pppd supports no IP address on ptp links).
You can really use ptp link without any IP address (in Linux)?
not me(yet) but look at pppd commit log http://git.ozlabs.org/?p=ppp.git;a=commit;h=eee67a89b6e5703a54a21ef835c383c1...
