If you do test large (and by large I'm talking about millions of znodes
and 10s of millions of watches) be sure to allocate enough memory, get
the latest JVM (1.6.0_17) and turn on incremental/CMS GC in the sun JVM.
You may find this helpful as well for tracking progress in real time:

Rt, this was with 1gE. No, I don't know anyone who has done this. But
it should be easy enough for you to test. Limit the amount of data you
are storing in znodes and it shouldn't be too terrible.
Ok. I will do experiments in a lab with 40 Core 2 duo machines, 2G RAM,
and a common 5400 rpm disk. Try to believe that ;) The data inserted in
nodes are quite small (<1k, 2k), but the amount of znodes and watches is
large.
Not currently, this feature is looking for someone interested enough
to provide some patches ;-)

Maybe in a near future! ;)
