[OpenLayers-Dev] Vector drawing

[Cameron Shorter]

Thanks for that email.
I'm not on the users list, so missed this message.

A vector rendering library like the dojo one is exactly what we should 
be using.

What issues do we face incorporating Dojo into OpenLayers?
Is the Licence ok (they use the Artistic)?

Is it technically the right think to do. OpenLayers uses prototype for 
AJAX support. Will that be compatable with Dojo?
