Re: Persistent Services Needed
One way to establish persistent services is to use the DNS for indirection: register a name for a service (or a set of services), which then point to servers of those services by a DNS name. If the service needs to move (hosts, net connections, etc), the only thing that changes is the DNS zone file and the references to the service through the name stay exactly the same. Hell, if your service requires no state information or can have replicated data (e.g. DNS, FTP, WWW), you can use "round robin" techniques with very low DNS RR TTL's to spread the service load over a bunch of widely distributed hosts. The NetBSD gang understand this principle: netbsd.org has several servers all over the place: E-mail to netbsd.org is handled at MIT. www.netbsd.org is served up by WWU.EDU ftp.netbsd.org is at CMU. Perhaps Eric Hughes can be prevailed upon to permit "privacy.net" to be used in this manner. Erik Fair

Sounds like a good idea to me. I've always kinda wondered why there wasn't a cypherpunks.org or something. It'd certainly make it easier for folks to find us... -- ========================================================================== David J.
