(Get the code!)
To your 2nd point: you are right, but I tend to follow the principle of creating something right before I need it..I do the same with variable initialization ;) Creating a port just for the sake of checking that we hit the quota limit sounds wrong to me. I grant you that there should be a number of quota checks at the very beginning of the spawning process, and port quota is definitely one of them.
To your 3rd point: it looks like that there is no sync of quotas between projects, and I am not proposing anything heavy duty. However Nova Quotas already has a reservation mechanism; maybe a first step in this direction may be to pull Quotas from other projects and cache them in Nova. The reservation may happen on the cached copy (that could be refreshed on request or periodically); not ideal, but it's a start.
