Bitcoin contracts

[juanjo75es]

Hello, I would like to know if it could be any objection about using the Bitcoin for uses not related with currencies. Like https://en.bitcoin.it/wiki/Contracts#Example_7:_Rapidly-adjusted_.28micro.29payments_to_a_pre-determined_party

I mean, it could be that miners wouldn't want to process this kind of transactions. How are fees applied to this kind of transactions?
Could anyone send me some more documentation about how to implement these transactions?

Regards
