1.More and more ISPs are deploying Carrier Grade NAT(CGN), since the IPv4 address space is already exausted. Meanwhile, IPv6 doesn't seem to be widely deployed.As we all know, a NATed IP address cannot accept incoming connections,which is harmful to any P2P application, including LN.Sadly, I'm currently posting under a CGN IP address...2.Ordinary people like me may feel difficult to keep a node up 24x7, but, AFAIK, LN requires any nodes on the "routing path" to be online, otherwise payment may fail, or fund may be "locked" for some time.3.Some big blockers threathend that LN won't be decentralized, since people will be strongly incentivized to open channel with "large scale LN node operator", thus, the govt may force them to give up accepting anonymous channels, or forbid them to use onion routing protocol on LN.I hope I'm not spreading something like FUD...I'll be appreciative to anyone who could resolve my confusions. via /r/Bitcoin http://ift.tt/2mcuKzG
