Practical Typography
I love this font, and I'll probably buy it.  I want the designer to get money for it.But, what is this about read only fonts?  If the browser can see the font then the browser can steal the font (I mean the program and the user of the program respectively).If it were my font I'd aim for detecting cheaters instead of preventing cheaters.  Maybe the font file can include an hmac?  When I don't need money, either after death or maybe before, I want them to steal my font so it becomes popular (more popular than Arial so the world will improve).  Until then I'll litigate, or publicly shame or whatever I want.Also this part of the license made me laugh (http://mbtype.com/license/):
"If you have unusual or excessive technical support needs, I can terminate your license by 
refunding your license fee."
