Yep. You can toss in sugar, salt, vinegar, etc and it will change boiling/freezing.

The "cavitation inception" I have heard of described as a nucleation source. That's why we put boiling chips in a beaker to control the boiling.

It is an entirely separate process than the colligative mechanism discussed above.
