Not sure about iPhone, but in OSX you can load fonts on the fly from a file, I've done it myself, I'm happy to share code if it helps

sweet! I hope it works fine, thx so much! Alternatively, maybe you could allow the user to upload its own fonts to the ipad, to overcome any licensing? I know it's quite some work, but it would allow maximum flexibility. Great product by the way!

What about ProFont? I use it in windows as a monaco 9 replacement, not sure about the license... http://www.tobias-jung.de/seekingprofont/
