Isolating and Analytical Languages

I really love the Vietnamese derivational system because it has two competing things going on. When an isolating language generally you don't really know where the word boundaries are. It's just kind of confusing and there's no good tests sometimes to tell whether something is an independent morpheme or not. Do you want to give people homework to make an isolatinglanguage? I mean if people want to I would be more than happy to see that. If we get something as magnificent as the last one but by a different person this time. That would be fine.
