[jQuery] got thoughts for watching a UL?


Wondering if anyone has some ideas on how best to monitor a UL (or OL)
for changes? At the most basic, I want the listener to know when any
LI's get added to it (removed does not matter), but it would be even
better if there was a superfast way to monitor the full contents for
changes (or each individual LI).
Thoughts? I'm looking for a very lightweight solution. Hesitant to setup
a timer and have it check LI count, but can do that if that's really the
best/only way.
This is for an enhancement to the jQuery listnav plugin we (my company)
release a month or so ago.
Thx,
Jack
