I wrote an RSS feed for our nethack server, which will keep you informed about player deaths and their scores. (Thanks Nick for the brilliant idea). The source is also available.
It does not tell you about deaths by quitting, so feel free to continue spamming new wizards/priests to get that spellbook of identify.
UPDATE: I changed the feed link from http://209.6.168.183:81/nethack_rss.xml to http://sadowl.com/nethack_rss.xml, which is now the preferred location, because the other one is impossible to remember. Both still get updated every hour, so if you’ve already added the former to your feed, you don’t need to change anything. Also, Swifty has already noticed this post and joined our server. RSS for the win!
