A few concerns;
1. It won't (reliably) work with DRBD because.
2. I never trust a fence method that requires the victim be in any way
operational.
3. If I have a SAN, I probably have a SAN switch and can do fabric fencing.
4. There is a similar mechanism already in the fence_* world;

So it wouldn't be right for me.
