Looking for users of IPX over IP tunneling

Dear all,

Over the next couple of weeks, I will be reviewing the set of non-MPSAFE 
network stack components in preparation for a status update to the arch@ 
mailing list.  One of the remaining components that requires Giant is the IPX 
over IP tunneling facility (ipx_ip).  I'd like to solicit users of this 
facility, if any, to work with me in testing locking patches I'm currently 
developing against FreeBSD 7.x.

I'm actually not entirely convinced this feature works, so would also like to 
hear from users of IPX over IP tunneling for this reason.  I've found a couple 
of bugs that would result in improper error messages being returned, etc. 
There's also a comment in the NOTES file that this feature is "not available".
