Looks like a great product, our only concern is the low number of pageviews/site/tier. So our questions are:
* If necessary, can we purchase more pageviews, and if so- at what cost?
* Do you have now (or is it on your short term roadmap) the ability to assign limits per site (e.g. if we get Tier 3 with 50K pageviews- can we set the limit of 10K/website/month)? This is likely a dealbreaker for us. We'd like to provide this as an add-on for our websites, but if the total pageviews is shared among ALL sites and there's no way to set limits, it's likely not the right tool for us to invest in.

Look forward to hearing back!
