OK, this won't mean much to many, but it is a product that I'd like to see more use of because it would be a light-weight way to share info at settings like GA. And without paper.
Did you see the story of the New Orleans health fair story on The News Hour with Jim Lehrer tonight? Did you notice the credit card sized discs the clients were given to contain their health info? Those were are so-called hockey rink CDs, or business card disks. They hold about 50 megabytes, the same as about thirty old floppies, but only a fourteenth of a full CD. Some tiny Linux distributions come on business card disks. They are little, can fit into a pocket, and some can be label-printed with ink-jet printers. Vendors often sell them in bulk, bundled with vinyl envelopes.
Consider the GA exhibitor who can "set up shop" quite nicely with a printed table drape (to the rear of the booth) and -- leaving the paper at home -- have representatives hand out these discs to passers-by. The printed label identifies the group, gives contact info and a web address. Fifty megs of data might be the outreach, depending on the group. The whole kit could be put in a suitcase -- perhaps even a carry-on -- and I have to think the discs are more likely to be used and not discarded than the bulk of what is picked up at conventions.
