Can we please get a reply to this prior to the IPO.
"So if I invest 1 BTC and get my 2,000 or so Ether, what happens when people start mining? Is some dude with a jacked up rig going to be able to mine 10,000,000 Ether in the first couple hours? How is this being handled so that my investment is actually worth something?"
#1 - we haven't announced the structure of the Ether sale yet
#2 - that's not how mining works, thankfully

Just like Bitcoin, inflation comes from mining. The amount that can be mined is controlled by the network, and corresponds to a fixed percentage of what was raised in the ether sale. This is mean inflation is rapidly decreasing year on year, eventually tending to 0.
