Leafnode?

Meanwhile, just to confirm, arbitrary header scoring did work, but only 
after downloading the messages and possibly manually triggering a rescore, 
correct?

Did you have to manually trigger the rescore, or did pan automatically 
rescore after it downloaded the messages?

And what size cache are you using?  I predicted that at least if you had 
to manually rescore, you'd need to have a cache large enough to keep the 
set of messages you wanted to rescore, so pan would have the information 
at hand when you told it to rescore.  I normally work with a multi-GiB 
cache and for binaries at least, after deleting the obvious no-interest 
posts I download the remaining messages to cache for further processing, 
so that wouldn't be a big deal here, but for people who keep the default 
10 MiB cache and routinely download and save in one go instead of working 
from cache, it'd be a big change.

Meanwhile (2), your idea of using a caching news server triggered another 
question I don't have an answer to.  Running a local caching news server 
and having pan access it is a setup most people won't have, but it does 
have some interesting implications, the most obvious of which is that pan 
could operate with little to no cache of its own (I'd probably run a 
small pan cache and put it in tmpfs, so as not to hit permanent storage 
at all in that case), since the entire server pan's accessing would be 
local.

But your comments triggered this thought process and question:

With control of the server as well, and thus its overview policy, you 
could of course put whatever headers your interested in, in the 
overview.  Can pan's arbitrary header scoring use such non-default-
overview-header content if it's available in the overview, or must it 
still cache the post in ordered to score on those headers, because it 
doesn't expect them in the overview and thus simply doesn't check for 
them at that point?

Interesting question.  The answer really doesn't matter to most, but it 
would to those with servers that have a relatively liberal overview 
policy, putting many headers in it, as well as to those who do run their 
own server, either remote or local, and thus control what's in the 
overview.
