I appreciate all the comments so far and am taking notes, keep them coming. What I see as the main issues are:

questions/issues:
1) cost effectiveness, can it be done cheaper and faster through local material
2) Logisitic support (transport and construct) sanity check-does it make sense?
3) Cultural sensitivity to: type of housing, location and ethnic composition (is it acceptable to the target population, even for temp housing)

benefits:
1) prefab power, water, sanitation, laundry facilities; schools, medical clinics and community center are all players, provifing a plug an play utility, far easier to slap a self contained unit onto the ground and have the locals run the piping and wiring than to cobble together the pieces ad hoc. You still utilize locals for the laying of foundations, the internal traffic grid, fencing and wiring, piping.
2) prefabs can be wired for sound--they can have many modern conveniences prebuilt into them, you can make selling this on the cultural side easier by defeating the skepticsim and indifference by offering a better life. You can also have prefab stores, maintenance facilites and restaurants for entrpeneurs. These could be organized as needed by the establishing agencies, possibly a PRT. There by providing job opportunites other than simple manual labor.
3) The intent is to draw people away from the borders and from the larger ciities (city) to create smaller more defensible/managable enclaves and to provide them a better standard of living-access to jobs/job skill training.

Notes:
1) If the resettlement village(s) were to be colocated or grouped near a PRT then the interaction with the government for support would be that much greater.
2) The current trend is to flow the population towards large urban areas were the individuals hope to find jobs and support from the government. What generallyt happens is the infrastructure becomes quickly overwhelmd and fails, creating large unsafe, unsanitary slums. In Iraq the issue is somewhat different as people are fleeing violence, but he result is the same they head to safe havens or percieved safe havens which tend to be ramshackle refugee camps, and or foriegn cities. BY rapidly building safe and secure resttlement villages within the affected state you can reverse the trend and prove the governments desire to help teh people at the same time.

Cost: the estimate is that Syria alone will spend over 1 BILLION dollars this next year supporting the Iraq refugees. This is just one state, would it not be better to spend the money and bring the refugees back into Iraq? The needs of the refugees are simple-safety, security and a place to live and work. Far better to build this capacity within Iraq than in a camp in Jordan. I look at the Palestinian camps as a motivator to not allow these camps to exist long term.
