The yEnc method will yield a 2x expansion for a bitmap image of

considerably worse than a 37% increase.
No, for any data. It is relatively easy to design a scheme that limits the
overhead to 1-2% no matter what the input. The question is which is worth more,
some measure of yEnc compatibility or having this guarantee. I'm persoally
somewhat ambivalent on this and would appreciate hearing other opinions.
