No, just consider that you would be willing to do it. When, if ever, the company figures out what they want. This job is good enough that if you aren't willing to even consider moving or commuting for a couple of years, you don't want it bad enough. I wonder how many people said they were planning on moving to Memphis during the interview, and never managed to end up there. Were they lying?

Cool about the $5K private school stipend. We've paid up to 26K per kid for private school, with no stipend. I can't imagine international schools are more expensive.
