What makes you want to visit Iran - doesn't seem very relaxing to me and there are lots of other interesting historical sites in the rest of the middle east and Europe. Assuming you are coming from the US?

Lots of technical questions but what exactly are you worried about - some systems you want to have access to or some data you want to hide?

I've travelled near the Iran border on the eastern edge of Turkey and the countryside is beautiful! Hope you get the break you're looking for!
