engine_environment is an expression like any other, but there is only one per engine with a well defined flow expression id. This id being the "primary key" of the expression storage, we just have to make sure that this storage can retrieve the engine environment expression among the other expressions. wfidgen.last, maybe, a file is OK though. > > There is one issue though : the engine is demanding in terms of > > updates to the storage.

Well, it depends, maybe your contract states that any idea/implementation you 'produced' during work time belong to the company...
