I agree. Originally I was in favour of the X-Pingback header over-riding
the <link> element as doing so would allow owners of static sites to update
all their pingback information but then I realised that this would confuse
clients that do not look for X-Pingback (they would see the <link> element
and be unaware that it has been over-ridden).
I just spotted the pingback-0.9.1 spec in the specs directory on hixie.ch
and it's description of X-Pingback looks spot on:

Cheers,
