Thanks for the suggestion, guys. We could definitely use genetlink 
instead of nfnetlink for the userspace-kernelspace communication stuff.

However, this still leaves us with the second problem -- registering a 
conntrack extension without recompiling the conntrack module. That one 
is still more or less a show-stopper for us, unless we implement our 
own state table effectively duplicating the features of the conntrack 
hash and do a lookup every time we need policy information. Neither of 
these options is particularly nice.
