wms clients

[Nate Reed]

I'm looking for a good open source web-based client to use with a web map 
service that is implemented in MapServer.  

My requirements:

- Graphical widgets for zoom/pan/layer selection
- Need to be able to add custom selections (time, discrete region, etc.)
- Animated time series
- Nice-to-have: continuous zoom and pan
- Access a map service in PHP MapScript or via WMS.
- Supports query by point for closest numerical values

I would prefer a JavaScript-based client but am curious: what's the most 
approrpriate client for the job?  I have looked at Community MapBuilder 
and ka-Map and they both look very nice, but I don't know if they can 
easily be modified or adapted for my needs.  Also, I don't know if these 
are production-ready clients.

Any input is appreciated.

Thanks,
Nate
