If you can't attend Black Hat conferences then Webinars might be the next best thing to actually being there.

The first Webinar was delivered July 2 and covers parts the presentations for Black Hat USA 2008. The Webinar is facilitated via a MP3 audio file and a PowerPoint presentation. There's also a mailing list you can join to receive notice about upcoming Webcasts, which will now be delivered every month. To joing the mailing list send email to subscribe-webcasts [at] blackhat (dot) com.
