Years ago I've saw a similar scheme in the UK but without the technology, it was called "The Green bike Scheme" and the idea was that there was all thee green bikes just left around and you could use them whenever you needed to. Of course most where stolen within the first week or ended up being thrown in the river, it was based on an idea from Amsterdam.

I like this idea as at least it attempts to prevent theft and vandalism. Mind you I would think you would need large amounts of stations at the work centers, for people coming in from the edge of the city. It looks good though and the presentation was nicely done.
