I'm really not a fan of subjective "mine is bigger than yours"
discussions. Just three comments that I try to keep as objective as

The last time I checked
had more than one entry.

That surely depends on the user and the task he has to do...

I think combination should be straightforward: "zoo" is general enough to
allow for time indexes of class "ti". Overall, "ti" seems to be
well-written and only some methods might need to be added/improved to
cooperate fully with zoo. Maybe some of the functionality that is
currently available for "tis" but is not available for all conceivalbe
zoo+arbitrary_index objects might be special cased for zoo+ti or zooreg or
zooreg+ti etc.
