Hacker Dojo work has caused me to run into a number of governments / entities with money trying to do things like this by either directly handing out cash or handing out goodies and tax breaks. One of the oddest/largest is in Vietnam http://www.quangtrungsoft.com.vn/

This doesn't prove it's a good idea, but it does help to realize that there are enough of these programs going that they can at least learn from each other's mistakes.
