Hi Paul, maybe I haven't searched very well the documentation, I'dd
certainly do it. I'll test the community very soon.

As I said I have tested only wms with no caching layer yet. Yes I'll
definitely try TileCache, I actually tried yesterday but I couldn't go
further the "pink tiles" stage, I'll have a go again today.

Well again, a proper comparison may be done when I have tested with a
caching mechanism, at this stage I compared a kaMap prototype with a wms no
cached OL so regarding my "slow" OL statement it has been  probably
premature. I need more tests for a full comparison. I'll let you know.
