I agree.  I also like to add that I see no big problem in continuing
to use the "http://my-flacky-company.com/~henrik" extension if the
server dies, or is taken over.  A malicious party could take over the
my-flacky-company.com domain and bind different semantics to the URL
rather than not serving it anymore, but I don't think this social risk
is much bigger than lots of other identity theft risks we have in the
internet.

I must admit though that, the more I think about using URLs as
identifiers, the more attractive IANA-based registration seems.  I
therefore plan to rework the feature tag registration draft into a
x:/ftag:/whatever: URI registration draft, which allows parties to
reserve chunks of a hierarchical namespace, so that people have an
alternative to URLs.

Koen.
