Actually, can you even link to a particular post by date? I think you
can link to a day, month or year, but not a post. So it looks like
it's either categories as permalinks or writing a plugin to do it
another way.

I'm not sure how best to write a plugin for this. Lets say we want
some sort of permalink IDs that are independent of either category or
date. We could use the filename or a #slug metadata line. Either way I
see two difficulties: 1. the user could potentially create non-unique
IDs and 2. I think the plugin would need to build an index of the IDs
in order to be able to respond to permalink requests quickly enough.

One way it could work is similar to the rdate utility. Before
publishing content to your blog you run a 'slug' script that adds
unique, short #slug metadata lines to any of your posts that don't
already have them. These could be numeric or based on the post title
or filename (with numbers added for uniqueness of necessary). The
script also creates an index of slugs. A pyblosxom plugin then uses
this index to handle requests for posts via their slugs.

I dunno, feels inelegant. Perhaps keeping categories fixed is better.
