Building low cost, section 8 shipping container homes

[Mark Albini]

This is an idea I've been throwing around a lot lately. There is a lot of development going on in my city and it is is all being pushed north. I've been thinking of purchasing a lot to build a 3 unit building made out of shipping containers. Just wanted to get peoples opinions about this idea. 

Does anyone have any experience with these types of constructions? Are there any major pitfalls to look out for? Do people think this is a viable way to build greener and more affordable housing?
