The CDs we distributed really served three goals.

1. As a complete brochure documenting all our products on the CD sleeve
2. As a physical artifact that showgoers can take home to remind them that we exist
3. And, obviously, to finally distribute the software itself

Although the discs fails on point 3, they are still serving points 1 and 2. Which is why finding a replacement for them (that is affordable in large quantities) is going to require a bit of thought. I have a feeling it is going to be a purely paper-based product though...

As for other statistics from LiveDisc, the 5.8% number is the only one we have, we don't track sales follow throughs or website traffic from it.
