You should offer an RSS-Feed! What do you think? Is this doable?
It certainly is doable. Several wikis already implement this.
Compare the recent changes list, http://susning.nu/Senaste_nytt with this RSS feed http://susning.nu/rss or its text version http://susning.nu/rss.txt (same contents declared as Content-Type: text/plain).
I'm not certain who actually uses it, but it was fun to implement.
Another way is to import an RSS feed into a wiki page, e.g. the RSS feed from Slashdot is imported into http://susning.nu/Slashdot just by saying [(rss http://slashdot.org/slashdot.rdf)] in the wiki page.
