Coming back to what Stefan actually asked, he may not have noticed the https://svn.apache.org/repos/asf/devicemap/whiteboard/ folder when he suggested something like https://svn.apache.org/repos/asf/devicemap/sandbox/ .
The way Sling uses "whiteboard" is comparable to Tamaya's "sandbox" folder, so either one would work, just gotta decide which one to use (or create if it's one that does not exist)
