It's from a letter from the TTARA -- it's currently behind a paywall (hence the reason for only excerpting it) but should be public very soon. [Edit: website - http://www.ttara.org/ ]
But even that is a private organization not representing the state of Texas. It would be nice to see an official statement and not 2nd hand unwritten statement on something so important.
Agreed -- however, the quote from the Director of Tax Administration is interesting as it specifically address the intent (or NON-intent) for these changes to apply to webhosting.
