Yes, I had noticed this after browsing through your documentation for the
program and immediatley bookmarked it as "hella useful"...

I was indeed, and had worried about the unique id issue. I'd like to get
your thoughts on it. My thoughts are thusly:

 - besides numbering, the unique id has no purpose.
 - if we can assure getting rid of duplicates, and 404's,
   then wouldn't the xmlUrl be the unique id, ie, if a
   channel changes a url, then the old xmlUrl would 404
   and be removed...

You mention that the ID would survive changes -
that sounds like more work to me, actually:

 - We go with a unique id system. A channel dies. Instead
   of removing the channel, it has to be put in a pending
   area so we don't lose the unique id number. The
   author contacts us with the new xmlUrl*. We now
   have to hunt down the unique id, and change the xmlUrl.
   To make sure the rest of the junk is up to date, a script
   downloads xmlUrl and reassign title/description, etc.

 - We go with the unique xmlUrl system. A url 404's, so
   it's automatically removed from the list. An author
   submits a url, a script downloads the url and assigns
   a new entry.

(*: I'm ignoring the extra time needed to make a web based frontend of RSS
modification. Should there be one?) Either way would still force us to
check the whole list for duplicate entries because overzealous authors may
pad the results (or else ignore the "we're busy. it'll take three days to
be added."). For simplicity sake, I'm also leaving out any mention of "if
channel has 404'd three times in a row, then remove".

Thoughts? (Sorry - this was a rushed email. I'm heading off to work).
