Internet Cafes in Ecuador

I am moving to Ecuador to do missionary work.

I will be supporting my family by continuing to run my business on the internet.

One thing I had trouble with while visiting last year was that I couldn't use my macbook in the internet cafes because there was no wireless access and the machines were running a program on windows xp that monitored and measured the usage time.

Does anyone know a work around that would allow me to be able to ethernet plug my mac into the network and use the internet? Of course I would want the internet cafe to be able to track my time and charge me their $0.60 per hour fee.

Thanks in advance for your help!
