Another source you might want to consider is GMW Associates. I haven't tried them yet, but they look interesting:

A "better" method of current limiting might be to just inform the driver that she is about to pop a breaker. Remember to include an over-ride if you do close the loop in software. A driver might need that little extra oomph, even if it means popping breakers a few seconds later. |
MaximIC also creates a few, I used a high side current sensor from them a few years ago when making an active load for a solar panel. I can probably find the schematics and code if someone is interested.
