Writing log files is easy. Displaying and manipulating that data in realtime when the datastore grows exponentially over time is most definitely NOT.

You cannot compare caching and displaying WordPress content with providing more advanced analytics and data logging that makes use of realtime data manipulation, reporting, and actions/triggers.

They simply aren't the same thing and anyone who thinks MySQL and WordPress is the ideal platform to more complex applications involving extremely large amounts of data hasn't tackled this type of thing before.

The developers at Stream obviously plan on taking things in a direction that simply running it locally on a $9/month BlueHost shared hosting account is not going to be able to handle and I can tell you from experience that it doesn't take very much to get to the point where your typical shared hosting account is going to run into major performance issues.
