It seems to me that you should be posting the version you have, not the
version posted on keyservers.

I'd do this by having cron run a shell script that exported my public key
and compared it to the copy that is already posted. If the two don't match
the new key would be copied over the local copy of the old key and would
also be uploaded to my web site:

#!/bin/sh
#
oldkey=$HOME/public_html/mykey.asc
newkey=$HOME/tmp/mykey.asc.$$

gpg --export --armor 0xNNNNNNNN > $newkey

if diff --brief $oldkey $newkey; then
  # no changes
  exit
else
  # key has changed
  cp $newkey $oldkey
  ftp $HOME/etc/upload_key.ftp
  rm $newkey
fi
# end of script


The basic FTP client that ships with Linux is scriptable. In this case I
assumed there is an FTP script that contains the commands to log into the
web server and upload the key. The script may look like this:

open www.myisp.com
user myusername
pass mypassword
lcd /home/username/public_html
cd /path/to/webpages
binary
put mykey.asc
quit


This script contains a password and should have it's permission set to
600. Alternatively, you could omit the "user" and "pass" commands by
creating a ~/.netrc file that contains passwords for all your FTP
accounts. The FTP client automatically looks for this file and uses it to
auto-login to remote hosts. man ftp.
