[Users] simplified geometries and layer scale dependency

Okay, sorry to be clogging up the airwaves this morning!

I have a 5MB geojson file that I've used a douglas-pueker algorith to 
shrink down to 55K for quick display when zoomed out. I need to show the 
full complexity when zoomed in.

I know I can set minScaleDenom and maxScaleDenom on layers in 
openlayers, or in my mapfile in mapserver, been doin' that for years!

how do I do that if I'm using a FeatureStore? I can think of a few ways 
to approach it, but I thought I'd ask the group if the there is a 
generally used, or canonical, approach.
Thanks again,
Percy
