I have a similar situation here; basically it would be nice to have a 
default crs for when one is not provided; I can think of two good ways.

a) A solution at the catalog level ...
- assign per url ... so all the services that have 
file:C///data//example/ ---> EPSG:3005

b) Solution(s) at the map level
- assign a default CRS for each map ... as a Map Property
- grab the map CRS and assume that is good ..

The existing solution (an application wide preference) is not so much fun.

So out of the above ideas what would meet our mandate of a "sensible" 
default?
