I agree with many of the previous posters that having the Projects function tied to only one customer is ridiculous. 

I also do the bookkeeping for multiple non-profits and we currently use classes and run the P&L by Class for each individual Project. It works, but I would really like it in a neat little package like Projects seems to offer. Another issue - do projects work over a multi-year span? We have many Grants that come on three-year contracts and it would be great to not have to be constantly adjusting the dates to see where we are at.
