As for the offer of KEY's
It looks like they are only giving out 10 key's
10 for technet and another 10 for everyone else.

I personally have 3 technet 32-bit keys (have the 32-bit ISO)
5 non-technet 32-bit keys (Can't seem to finsh the download)
5 non-technet 64-bit keys (Have the 64-bit ISO)

And everyone else I've talked to also has the same set of keys...
