A word of warning is required, however. At MacWorld we gave out roughly 5,000 discs with LiveDisc on them. We set our LiveDisc to ping our web server to allow us to count hits. Of the 5,000 discs we gave out, 5.8% were ever used. That may seem a bit low, but it gets quite depressing when converted to an absolute count: 288. Out of 5000 CDs given out, no more than 300 were used - perhaps giving away CDs isn’t the best idea after all.
LiveDiscKit looks seriously cool, and I was about to download and give it a try (open source, to boot), just because it looks fun. Then I remembered that my MabBook Air doesn’t have a DVD drive, and in over four months of ownership, I never missed it once to bother buying one. Count that as a data point.
