A few products that I know are in Howie's black hat lab. I don't have access to his lab but i'm on his mailing list so I hear him talk about whats in there.

1. Bookmark generation - Social Bookmarking.
2. Twitter Automation - Building hundreds of twitter accounts and posting to them on auto.
3. Ping Tool - Pings rss feeds to over 200 ping sites and also submits RSS feeds to 100 sites.
4. Keyword addiction - Keyword tool.
5. Info creation - searches through all the top sites like flickr, yahoo answers, wiki sites, google trends for info.
