A message I sent to mapserver-users -- this is essentially a summary of
what I was talking about with changeParams last night.

Implementation in OpenLayers:

Thanks to David for kicking my butt to get it done, and giving
me an example to copy from. OpenLayers now has support for changing
parameters on layers after they're added, which is a useful feature for
lots of things like this: for example, one could change the 'layers'
parameter in javascript code, which was not possible before.

Thanks!
