Which to me is a perfectly acceptable behaviour. It's just like any other connection then, you'll have to initiate another connection after a certain timeout.

And about the statistics, it's very much not scientific, but gives a good hint about the probability of this hacks success.
NetGear and D-Link being the absolutely most widely used routers for poor DC-geeks works very well it seems. And Windows being the most used OS especially among DC users works to 100%. This on UDP. So I'd like to say that at least 85-90% of the current passive users would support this punching, but since it takes two to tango - the percentage must be squared, so about 70-80% success in the end. Good enough for me. But this definitely needs testing before I can open up the champagne ;)
