sorry, I forgot:

       3- Factor out all your direct accesses to Node internals into a custom module/Builder, and then wrap it with a check for the 
SCons version. For 2.3.x and smaller, you access Node attributes as before, and for the newer versions you then branch to using the 
getter methods.

This is pretty much what the compat layer would do, which I mentioned in my last reply.

Best regards,

Dirk
