Yes, we received a lot of code from the Netscape purchase. This
included the directory server, cert server, mail server and calendar
server. Right now we're concentrating on building a community around
the directory server. We're evaluating the source code for those other

decide to build projects around the other parts, you'll hear about it
when we're ready.
