If you're not averse to creating a little helper class, why not
just write a custom file selector that can read your delimited
file. Then you can just leverage the built in resource collection
mechanisms like:

<files id="myfiles">
 <custom classname="your.new.custom.csvfile.reader.Selector">
  <param name="file" value="/your/files/location"/>
 </custom>
</files>

As of 1.7 this <files> item can be used just about wherever the
older <fileset> type was allowed...

WARNING: I have not worked with the new resource collections in
1.7 extensively; so not sure *exactly* how this might work.
