How long of a period are we talking about? I would be willing to run a build that did this for 1-2 weeks (I used to use the testnet, but it was impossible to find peers). I don't know if it would need to be a mandatory build, but if so you should give people notice that '"'whichever build #' includes this tracking info, if you don't want to use it turn off your node for X days". That being said if you were to release an optional build that didn't autoupdate I think it would be best... I may disagree with what you have to say, but I shall defend, to the death, your right to say it. - Voltaire Those who would give up Liberty, to purchase temporary Safety, deserve neither Liberty nor Safety. - Ben Franklin -------------- next part -------------- An HTML attachment was scrubbed...
