Shouldn't it only be considered cybersquatting if the owner of the trademark doesn't already own their primary domain (read: .com)? I mean, it's not really cybersquatting if you own the .net, but ESSO already owns the .com. This is like saying that every trademarked company should be able to own EVERY TLD for their trademark (which mosts decide is not necessary). What is the purpose of the lesser TLDs (.net, .org, .cc., etc.) if not to give the Internet some diversity? By allowing someone else the opportunity to own their own acronym (the East Springfield Sewing Organization, for instance) as a .net or .org is the very basis for even having multiple TLDs in the first place -- and should not be considered cybersquatting. Of course, this breaks down as the length of the domain increases (i.e., owning disneyworld.net is a bit different, since the chances of having an acronym that is 11 characters long that matches d.i.s.n.e.y.w.o.r.l.d. is much lower than a 4 character acronym like E.S.S.O.)
Anyway, that's just my $0.02.
BTW, Manu, have you even RECEIVED a C&D letter for this domain?
