I just added the code to drop the GGEP data from pongs to SVN. I have no tested if it works correct, can you please do this...
You can get the changes directly from the Phex SVN or sometimes tonight or tomorrow from our automated build system (in case its running correctly):
Index of /snapshots
I only did this change because it was quite easy to integrate, though actually I don't believe it is necessary to still support outdated nodes that don't yet support GGEP extension...
