Heh... I remember having an internal dns server with zone files for a whole bunch of internal servers using $our-real-domain-name.local as dupes of $our-real-domain-name.com. Then an early OSX upgrade brought in Rendezvous/Bonjour in maybe '02 or '03 - and all the Macs stopped being able to find the local machines... (And the sysadmin who'd set it all up didn't believe the problem reports at first, 'cause her CentOS machine were still working just fine.)
