4.0 is most stable currently, though the last few days I've been committing a lot
of barely tested code.  Will test this better shortly.

And, sorry, but I don't have time right now to help with making this work with
OpenWrt.  At the least, it is liable to not be trivial.  Search the list for
'CT' + 'OpenWRT' an you may find some help...others have posted patch-sets
for OpenWRT that includes at least many of my patches.


Thanks,
Ben
