Is there a limit as to how many apple TVs i can connect to 1 iTunes account? Im speccing a house that has 8 individual TVs. The plan is to have an apple TV local to each TV. Will i have an issue with limits as to how many apple TVs i can connect to 1 iTunes account ? 

Im based in the UK, not sure if that makes a difference in relation to the terms &amp; conditions that govern this.
Use Home Sharing in iTunes, and sign into each ATV's "iTunes and App Store" account setting with the same account, and you'll be all set.  You can also set the ATV's to require the acct password to purchase content (or even to download free content), so you don't have to worry about guests/kids/etc purchasing content.
