I want to publish a typeface I’m working on (which I hope will form part of a small family) and need to include a license. I’ve been trying to find an appropriate free license, along the lines of the GPL/copyleft which might cover any nasties/abuses happening later.

I’m aware that there are issues with GPL licenses in fonts. (See here: http://www.typophile.com/node/31738) So it needn’t be a GPL license. I just can’t find an appropriate, simple license text specific to font distribution.

Essentially it needs to cover my free distribution, future free distribution (license intact) and my copyright.

Anyone with a similar license they use?
