Same goes for the server engine, 
I could also use it in the server engine, but did not get around to make this a project to let be implemented by the mothership (of course paying for the effort)… That said, I might be wanting to take this up again and cough up a couple of $ in Q1 next year (for the server engine, that is).

Cheers,
