Also worth noting :- If you are unable to make it to HOPE (I have never attended the conference myself) you can still benefit from it.

The folks at 2600 who organise it do, eventually, when energy and resources allow, post recordings of most of the conference talks online for all to enjoy. It does sometimes take several months to a year, but given they do so for free one cannot complain. These can be found on both the internet archive and youtube. 
2600.com also sells complete sets of audio and video recordings for download and on flash drives for convemience.

The talks from this year's HOPE won't be online for a long while after the conference but recorded talks from previous HOPE conferences both technical and not often remain interesting and relevant, especially given some of the individuals that regularly talk at the conference.
