Seems a good starting point

Good :-)

Well, it's your time, so you decide :-) Actually i think the possibility to 
load from a file or somewhere else a pre-specified set of exercises is more 
interesting than the Lab feature, but that's my non-teacher 
non-anythingRelatedToTeaching point of view.

Sebastian has not been working on kbruch since 2005.

I'm not saying his opinion is not important of course, but i'm not sure he 
still even reads this list, so don't wait for his OK.
