[mapguide-users] Displaying shp runtime with session user

[Kenneth, GEOGRAF A/S]

I'm not sure how to create SHP files using FDO, but you can always take 
an empty one, and copy the file to a new name.
Then you create a feature source for the new SHP file, and FDO 
insert/update etc. goes on as usual.
In the developers guide, the steps to create a runtime layer are 
explained. (basically extract layer xml, modify xml, save layer xml 
under new name).
I think Traian mentioned that SDF is faster, which makes sense as it 
utilizes the SQLite internal tree structures to maintain a spatial index.
