But there are much better ways to handle this kind of 'early-access' testing. It's not rocket science. Hell, it's only blockchain science.
Here's what you do:
* Fork the main chain to a testnet
* Invite your privileged few to help you test it on the testnet.
* When testing is complete, discard the testnet chain!
IT'S NOT THAT DIFFICULT! This 'privilege' bullshit is fucked up. Don't do it again.
Final point:
* After tested to satisfaction (on the discarded testnet chain):
* Simultaneous public release to everyone (including heatwallet.com and heatwallet download)
* Coincident announcement on all major channels
You have to get this right in the future. Early access to a privileged few is reprehensible.
