It used to be that all urls were passed to the new domain, which is in fact 'sporner.dyndns.org' (or sporner.dnsalias.org), but somehow it isn't done that way any longer. I will end up moving my domain to dyndns and this will be solved, but for the moment just use the following URL: http://sporner.dnsalias.org/freebsdclusters/frep >What it is: > >Well it's a start of a directory replication scheme.

The idea was to allow processors (or nodes) to be managed as a community resource that services could be dynamically instantiated (on demand) and since everything ran as a service they could be located anywhere, with the message layer being the conduit. I later realized that it made no sense to continue this work because of all the systems that exist it didn't make a lot of sense to create yet another one--except for ego reasons, which is not enough. So instead I got on the idea of process migration using an existing system, which is where things are now. In retrospect the first idea might not be a bad one when it comes to clusters of hundreds of machines, but I decided to go this way, which is where things will remain for now.
