1. I haven't found hotshot support in either Zope 2.8.1 nor the TRUNK.

2. Has I wrote, coverage.py can be used interactively (at least, from the 
command line) to focus on whichever package you are working on at the moment. 
You can also collect data from several runs, which is useful for us because we 
have to test each CPS package in a different run.

3. I understand that trace.py and coverage.py have some overlap, and should 
probably be merged into one great and up to date coverage tool. But before it is 
done, I find useful to have both tools at our disposal.

4. Same for hotshot and profile. Both are useful.
