Hello. I have a MSDNAA subscription from my university, and I have some questions about it.
This is mostly about the Vista SP2 integrated ISO not appearing there, but these are general questions too.
I know Vista SP2 integrated ISO appeared on TechNet and MSDN, but I was waiting for it to appear on MSDNAA too so I could download it. But there has been nothing so far... I know that when a new product appears, the teacher that supervises MSDNAA for my school has to enter an admin page and approve it so it can be downloaded by the students. I have spoken to the teacher and he said that Vista SP2 integrated image is not available. There is only Vista Business, Vista Business with SP1, and Vista Enterprise in the same flavours.

First. When a new product is available for MSDNAA, is it available to all the members in all the world at the same time no matter where they are from?
Does Microsoft make any difference between schools in different regions?

Second. I know that Windows Vista with SP2 integrated ISO is available for MSDN subscribers. Shouldn't it also be available for MSDNAA subscribers?
In general, how long after the initial release of a product does it appear on MSDNAA?

Third: The software that is on MSDNAA, is their ISOs exactly the same as the ones from MSDN and Technet?
Does Microsoft modify the ISOs that are put on MSDNAA? Or are they exactly the same as the ones from MSDN and Technet?

Fourth: I clicked "Details" on the MSDN page for Vista with SP2 ISO and it said it was available to the following levels of subscribers:

That includes "Developer AA" which I am a part of. And still, it is not available for download. Why is this?

If there is anyone who knows how things work regarding MSDNAA, I would be very grateful if they could answer my questions.

PS: I know you guys are all about customizing Windows and integrating hotfixes and stuff. I don't want to integrate SP2 in my existing SP1 ISO, I want it untouched from Microsoft

My MSDNAA account only shows Vista Business at the moment.I would think so. The Windows 7 RC showed up on my MSDNAA just a few days after its initial release.Not sure.
Yes, it will be approved eventually.I would say at the same time that it appears on MSDN, but it has to be approved by a school administrator like you mentioned.
Yes.They should be the same ones as far as I know.
Each school has its own MSDNAA page which handles authentication through its own servers (at least that's how mine is). As I mentioned before, an administrator has to approve the release of software on the MSDNAA page.

Thanks.
Also, is there a place where I could see the software posted on MSDNAA, except for my university's site? So I could check it out every once in a while and see what's new there. My university's site just lists an alphabetic list of the software, so I can't see what's new, and what was posted when.
