As for shares, I doubt the info will start getting sent before everyone has been paid. Why? You provided a payment address. If issuers knew your address, you wouldn't be able to distinguish between GLBSE's payment and issuer's payments. Which doesn't mean it's not going to be released soon. Hopefully everything will be processed within a few weeks.
That requirement was completely removed. You can log in to GLBSE and simply provide an email + BTC address.
As someone else brought up if Nefario had simply stopped deposits and disallowed trading it would have achieved the same result without the issue of double payments. I hope Nefario has some spare btc because I aint covering his screwup.
