No, I expect users who want to run services that listen on ports (which makes them not "average!") to know about those things.
You mean like the "server-less" P2P console games that elect the host from one of the current people in game?
Unless you want to reinvent uPnP for v6
What are you talking about? PFSense supports IPv6 uPnP with the base install. Just enable uPnP service and it will allow uPnP to punch holes in the firewall for the requesting IPv6 address. Worked just fine with my Windows box and Torrent. It was quite turn-key. Enable service, done.
If, however, time slows as it approached the blackhole and the particle never actually crossed the event horizon
Can someone please explain this. It seems to be accepted that not only does the object's time slows down as it approaches the event horizon, but it's velocity does also. I don't get that. If an object is moving away from me at 0.9999c, I could expect is to actually be moving away from me at that speed, not slowing down relative to me. If from my perspective an object has stopped moving, then it is no longer moving relative to me and its time should be pretty much the same to my reference.
I seem to be missing something. I assume it has to do with gravitational fields instead of "proper" velocity.
Any light emitted from the "black hole" itself could also be dwarfed by the noise of all the other em coming from the accretion disk, making it nearly impossible to detected remotely.
