The past owner was John Zuccarini. He used the alias Peter Carrington and an alias company "Party NIght Inc.", as per this report at Harvard U.:
http://cyber.law.harvard.edu/people/edelman/typo-domains/
"Of the domains reported here, most or all are registrations by John Zuccarini, doing business under multiple names including Mars Attack, Music Wave, Party Night Inc, Phayze 1 Phayze 2, and RaveClub Berlin. These many names (and their associated invalid WHOIS data) make it difficult to determine whether any given domain is in fact registered by Zuccarini, or whether domains were instead registered by others, but the author has endeavored to report only domains registered by Zuccarini."
While I do not contest Luc's claim that he emailed the person and offered $15K, I am surprised that he received a reply as John Z. was arrested in early Sept. of 2003:

The email address listed on the WHOIS for KazzaLite.com/KazaLite.com was:
oofeelssogood@clublife.nl
Clublife.nl was a free webmail service offered by a company that also runs
www.balistic.net
When I emailed them back in March they said that they had deactivated the webmail service long ago and that there were no active email addresses.
I had tried to buy these names in fall of 2003 and that is when all of this research came together. At that time the email address was dead and the phone number was inactive. I imagine that this wasn't by coincidence as John Z probably had these domains grouped in an account at a registrar and didn't care if the email/phone worked - and probably didn't want them to work.
If anyone replied to you Luc saying that they wanted $100K it sure wasn't 6 months ago -- unless you contacted John Z directly somehow while he is in jail.
