not a formal contract, but I believe there were rules that one had to
agree to.  Someone posted the docs a week or more ago on ARIN list, I
will try to dig up the links.

I'm not sure.  If Org A DID sign an agreement with IANA, and then IANA
delegates part of its job to Org B (the RIR), then I think that the
RIRs MIGHT have a moral ground upon which to act against a "bad
actor" ground...not so sure.

ERX (Early Registration Transfer), Can we call these legacy? I think not!
