CDR: stego for the censored

I'm currently looking for a way to get encrypted data via stego to people who live in countries where crypto is illegal, and who may be watched. so just sending them a large graphic would likely arouse suspicion. the 2 best solutions I've come up with so far are porn and spam. both are readily believable, even in large quantities. the problem with porn is that it may be illegal in itself in the same countries. the problem with spam is that ascii text just doesn't offer much to hide stego in (whitespacing, etc. is both easy to find and can store very little data).
