Ncat/nsock TTL feature request

Hello,
ncat it's really a powerful tool, I use it quite everyday, really
thanks for this cool project!
For some network tests (e.g. NAT traversal hole punching) I sometimes
need to choose the TTL value (IPv6) or hop limit (IPv6). Why don't add
the possibility to choose this value in ncat using, let's say, -T
<value> option ?
Implementing it shouldn't be so hard since it's just a setsockopt like:

setsockopt(sock, IPPROTO_IP, IP_TTL, &(ttl), sizeof(ttl));
or
setsockopt(sock, IPPROTO_IPV6, IPV6_UNICAST_HOPS, &(ttl), sizeof(ttl));

nsock should also be modified.

I would send the patch by myself but I know nmap/ncat more as a user
than as a developer and I'm still reviewing the code.

Anyone else supporting this feature request?

Thanks
