Is there an 'early warning' mailing list for up-to-the-minute alerts about in-progress DoS attacks, portscanning, etc?

The for-profit security companies, e.g. McAfee, Computer Associates, Symantec; frequently issue alerts via Businesswire and PR Newswire. They seem to compete with each other on who can get a press release out first. Although its not real-time, the NIPC puts out CyberNotes every two weeks. Its a good summary of what's happening. Look in publications on the http://www.nipc.gov/ web site. There are a number of real-time intrusion detection projects underway. The good ones seem to fade in and out, and focused on a single customer base. But I'm not aware of any which feed real-time reports to a public list, such as the case for spam hunters.
