The Kisha project looks interesting. It could probably use it for creating a client/server setup for the engine. However, on my current production host I can have only one rails application at a time. > I don't know if you are using ThreadedDbExpressionStorage or its > parent class DbExpressionStorage.

I now use the DbPersistedEngine without caching. The processes advance slowly (based on human interaction) but with many instances running at a time. Therefore caching would probably be not very efficient anyway. > filesystem instead of the DB.

I choose db storage because of crash recovery (the db server is shared, clustered, and frequently backed up). But file based storage should also work fine.
