I think a CD might be very good - look at the success Clive Lever "WildRover" has had in raising money for BCAB (the British Computer Association of the Blind) with the "Guide Cats for the Blind" CDs - thanks to Les Barker's generosity with his poems and the input of many talented performers and the distribution of the CD on a semi-pro-bono basis by Richard Ellin.

Distribution and promotion are the big parts of that jigsaw, but content will be important too.
