It's not every mouse movement -- just when the mouse stops for more than a tenth of a second. I do it for an application at work and find it works brilliantly -- in fact, I actually like the behavior better when there's lots of data than using a hover handler on a selectFeature control. A selectFeature control will *always* 'do the needful' -- even if you're just passing by. A hover handler requires *intention*, and I think that works very well. The round trip request time for talking to a server for the equivilant of a getfeatureinfo request against a table of 7 million rows is something like 130ms (hooray for PostGIS) and then we can display information in a little popup. I really find it works well. "Don't knock it til you try it."
