This is a bit awkward since there's no obvious way to get the inode of
the peer socket.  The best you can do is hope that it was created
immediately before the corresponding fd in the X server.  So, something
like this:

---
#!/usr/bin/python

from subprocess import Popen, PIPE

client_sockets = []
match = 0

ns = Popen(["netstat", "-an", "--unix"], stdout=PIPE)
output = ns.communicate()[0]
for line in output.split('\n'):
	if line.find("X11-unix") != -1:
		match = 1
	elif match:
		match = 0
		inode = line.split()[6]
		client_sockets.append(inode)

lsof = Popen(["lsof", "-U", "+c0", "-w"], stdout=PIPE)
output = lsof.communicate()[0]
for line in output.split('\n'):
	try:
		inode = line.split()[7]
		if inode in client_sockets:
			print line
	except:
		pass
