I am a "guy in Germany" who mapped some cities in *Iran* (Mashhad [1], 
some major streets of Bandar Abbas + complete island of Hormuz [2], 
major streets in Shiraz [3]). I had the help of some locals who supplied 
some names for places and streets. I guessed the initial street 
categories from the satellite imagery which worked quite well. Mapping 
the road network layout even without categories and names takes about 
70% of the work of capturing the streets in my opinion as adding names, 
categories and restrictions is lot less time-intensive once you have the 
ways already.

Happy tracing...  Don't forget about northern asian countries like 
Casachstan, Usbekistan, Turkmenistan... They have hi-res Yahoo coverage 
as well.
