+From: Jason Smith <jason.smith@canonical.com>
+Subject: add new extension point in GIO for use with multiple applications
+
+I am providing here a patch for GIO which opens up a new extension point. This
+extension point is useful to do quite a few things, however its primary target
+is a window matching library called wncksync. Wncksync is used to match windows
+by the XID to the .desktop file on the system they were launched from. With
+this patch wncksync becomes incredibly accurate at doing this, having very few
+flaws. Additionally the Zeitgeist developers are aware of this patch and intend
+on using it to improve their application as well.
+
+I will keep this short as I am sure there will need to be a conversation here
+about the patch, its implications, if and how to include it, and of course the
+code itself.
+
+Cheers,
+Jason
