Fair enough. I did have one other idea though: Will Topics accept parameters
passed to them? Put it another way, will we be able to build dynamic topics?

Another idea: Will it be possible to 'Topic-ize' the results of a ZSQL method?
they return a flat list.

I had a light go on: I can use Topics in combination with the Calendar tag and
acquisition to build custom calendars!

Given:
/root
  /Topic_1
  /Topic_2
  /Topic_3
  /Calendar

A URL like /root/Topic_1/Topic_2/Calendar/ should be valid and show me events in
both Topics (or categories, whatever)!

I can also see Topics being very useful in constructing heirarchical product
catalogs...

Cheers, all, and keep those ideas flowing!
