bcc, I share your concerns, except I don't think the coins will be devalued by botnets, there is a finite amount of coins.
If there is ever going to be a micro payment system it is going to resemble bitcoins regardless of who implements it.
The issue here are fees. When you are dealing in penny profits you can't be losing pennies to fees, unless you decentralize the payment process you are always going to have someone trying to collect fees from you.
