Armory to Data Miners - It's ok!

I finally got around to looking at the recent batch of armory updates, and noticed this little gem:

XML file size reduction: The XML files used by the Armory have been optimized for speed, partly by streamlining the amount of code in the files. As a result, third-party sites that mine Armory data may need to make adjustments to account for the new file configurations.

There you go, implicit permission from Blizzard to suck down data.
