Thank you.
You're most welcome.
That sounds very good.
It does, doen't it?! And... it actually is!
Just to be sure: when enrolling I pay 560 (same price as for Brazil) and get licenses for Windows and MS Office Windows Server 2003 etc. Does the same 560 include 5 licenses for Visual Studio in the MSDN Universal?
Yes, you get what is now equivalent to the Universal subscription. But now it is called Premium... those marketing people, you know them... Anyway, it comes with more than you can handle, my eyes shinned when I saw all those DVDs arriving... and the download area is like been closed alone in a candy shop! 
And this is it, 5 licenses to Visual Studio and others.
The site says you have to reenroll at the end of one year. Does that include a new payment for each additional year? What are the gotchas?
This is correct. As it looks like, you can reenroll for an additional year. And I'm not sure, but I would expect that we have to pay again. This is Microsoft, remmember? Well, if I were in their place, I would certainly charge too. There are no "gotchas" (am I too naive?), they only ask you to develop and market a microsoft solution, using their tools. From this point, you might climb the Microsoft Partnership program, I think.
Abraços.
