Tomorrow's (Thursday, 3/24/2011) nightly IDV build will support the

stridex = the X skip factor (stride)

bbox = the geographic bounding box (N,W,S,E)
For example:
<isl>
<datasource

stridex="1" stridey="2" stridez="1" bbox="40,-113,20,-98"/>

should be:
<isl>
<datasource
url="dods://motherlode.ucar.edu:8080/thredds/dodsC/casestudies/idvtest/grids/small_ruc_grid.nc"
stridex="2" stridey="3" stridez="2" bbox="40,-113,20,-98"/>

would select every other X gridpoint, every 3rd Y gridpoint,

Stride values are:
0 - undefined
1 - all points
2 - every other point
3 - every thrid point
etc.
Sorry for the confusion.
