Actually I have quite nothing: it is a system to export a WMC from the 
WMSManager, but it doesn't allow any import yet.
I was expecting to wait until the debate on WMC integration on 
OpenLayers would end, but I think it's somehow hanged...
I guess (and really hope) that FOSS4G Code Sprint will be the right 
place to do the big step with OpenLayers reagarding WMC import/export 
and SLD editing. Otherwise I'll have to start again on my own.

I'm sure we will face some limits to WMC

we started up with a page on OL wiki but it's just a first step:
as you can see there are no references yet to KML and to needed 
improvements to WMC (ex: layers visibility).
If you can help enhancing this page, you are welcome.
