unfortunately a flat rate cannot be used, as we expect users to be very different: e.g. we might have big companies with several users that belong to one billing-user and this billing-user would need several TB per month and a lot of CPU time and on the other end of the scale we could have a

If I write an application on AppEngine that supports multiple users, I'll get a bill at the end of the month for the complete app, right? Is it somehow possible to break down this cost to a per-user basis? i.e. I'd like to know which of my logged-in users has caused how much of the total cost?

you cannot use memcache to reliabliy increment the counter - it's just a cache and thus there's no such thing like a transaction (AFAIK) the memcache only makes sure, that a single put and get are atomic the problem arises in this case: 2 users call the same servelt, but these 2 calls will not

in this article http://code.google.com/intl/de-DE/appengine/articles/paging.html the author points out the problems that arise when you use a field that may not be unique for paging. the solution is to use a sharded counter over the user to make the field unique. Very fine until here. But then
