Forum OpenACS Development: Re: Is the OpenACS Patch Tracker (part of Bug Tracker) still being used?
For the suggestion of the host-node-map: sure, it is a useful extension to check the name lookup, at least for the near future. In general the host-node-map has several shortcomings and needs some rethinking. In particular it should be integrated with the virtual server capabilities of nsd, but that is a larger project.
