A neat opportunity. Good luck puzzling out the right answer.

One suggestion: research the local currency vs the dollar and other major currencies. Figure out which one balances cost of living there and protection from inflation historically (probably the last 10-15 years). Contract to have your salary calculated in that currency.

A friend accepted a job in Italy in the mid-90's. He didn't do this, and got paid in lire. It wasn't pretty.

Congratulations on having the offer.
