Assuming your local X extension is regular, it should be relatively easy
to describe in XCB's XML format. See the SHAPE extension description for
an example:
http://cgit.freedesktop.org/xcb/proto/tree/src/shape.xml

Once you've got that, you've got everything that XCB gives you:
automatic libxcb generation, automatic python binding, etc.

In terms of Wireshark, you "just" need to
 - Build unmodified wireshark from svn, to make sure you have that
process working.
 - Apply my patch from
https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=2981
 - Follow these directions:
https://bugs.wireshark.org/bugzilla/attachment.cgi?id=2492
(except replace the xcb/proto git clone URL with your local git
repository that has your own extension added to it)

Wireshark has excellent filtering capabilities. I'm sure you could
easily construct a filter to show only the packets you are interested in.
