Having thought about it... how can DNS help to make it more scalable? DNS does 
not scale because the DNS servers have the fastest databases on earth and the 
protocol is so fast. If you have 20 Million users/hosts in the .kde.org 
domain the DNS server still has to search through all 20 million users/hosts. 

DNS scales because you can distribute the entries. So if you have 20 million 
users, you can create 20 subdomains like hans_mayer_kde_org.subdomain.kde.org 
with 1 million users per subdomain. But you can do exactly the same with 
LDAP, AFAIK. So I dont see the point in introducing DNS and its additional 
complexity.
