That would be quite good as long as the emphisis is on 68k (and maybe old PPC) Macs, and as long as the site is fully compatible with these. e.g. I would expect to be able to use it without problem on a 68k Mac.

I agree with paws that some kind of programme which could be run on the computer could be used as an alternative to the web. I'm assuming you mean something like Hotline, but for a specific site only?
