I know it is not a good idea to base a design on a specific case, but 
attachlist does almost exactly what I want, so I would propose to add a 
"little" bit of wildcarding.

I am uploading the PDFs of a bunch of papers from a conference to a wiki. 
They have names like:
*subject A revisited.pdf (with a PowerPoint PDF called "subject A revisited 
PPT.pdf")
*paper 395 - a generic whoozit.pdf
*20050713_231.pdf

But I am quite willing (eager, in fact) to name them consistently with a 
date, paper number, and a bit of subject, so:
*20050712_123_subject_A.pdf
*20050712_123_subject_A_PPT.pdf
*20050712_234_whoozit.pdf
*20050713_231_lone_wolf.pdf

I then want to be able to specify subsets of the papers:

(:attachlist name=20050712*:)  would list anything starting with 20050712, 
or all the papers from the 12th.

(:attachlist name=20050712_123*:)  would list all the bits associated with 
paper 123.

This would then give me a nice listing with the file name, its size, and 
the date it was modified. The asterisk could be eliminated, but it makes it 
explicit that the name string is the start of the filename.

Another way I could solve this problem would be to have page-level upload 
directories with one page per paper, but then I lose the "per day" possibility.

Matching on the start of the filename is good enough for me because I can 
just prefix the files with strings that sort and display as desired.
