I am actually really digging this idea. I hope you're still up for it in a couple of months - after my move to Portugal - as I'm seriously interested in learning Japanese or possibly Chinese. I also like the idea of helping you out financially, so it would be a win-win situation. Anyhow, let's chat about this at a later time :>)

P.S. I hope there's still space in my head for another language. I will need to learn Portuguese too.
