GetEventStoreRepository Snapshot/Memento demo code

I am looking at the C# GetEventStoreRepository demo code, and it hydrates from the very start of the stream.

Is there any demo code available (or blog entry) that uses Snapshots/Memento that are stored after N number of events?

The blog here mentions snapshots saying if demand is high enough there will be a post - was this post ever created? :slight_smile:
