Hmm. Didn't know the 2 out of 3 rule with copyrights. I'm a singing guitar player so my charts serve the lyrics and therefore would be a problem to post. The whole PDF approach is interesting and I'll look into it.
In the meantime I've use GoodReader to download the Word docs to the iPad and it's working pretty well. Nowhere near as cool as the iReal Book app but c'est la vie.
Thanks
