You need to limit DOM elements. WMS with a query-on-click works for
that. of course, showing 1000 features won't just be a problem for IE --
it will also be a problem for FF2, mobile browsers, eeepcs, etc. 

Anotehr thing I do (on the OpenStreetMap homepage) is load the data,
then ask the user if they want to show it, if it's more than 100
features. That way, they hae the option of making the determination of
whether they think they can load it -- or the optino to zoom in further
if that's what they want.
