I'm not talking about "Micropayments" per se.
What is meant is more known as token-based payment in the US I think.
User loads between $20 and $80 USD into his account and gets say 2000 to 8000 (or more as bonus if you want to emphasis less, but larger payments) "coins" virtual currency that he can spend on the site.
Now you can attach a value to a picture, a message, value per second / minute of video etc. and like this and with clear, exact previews of what he is about to pay for he will consume much more than you'd ever dream of with "29.95" - and the beauty? He will not mind, as he gets exactly the tailored content that he wants to consume.
