Any other Details with STR #4169: Add support for PIN, "follow-me", and paid printing?

[Paul Conklin]

I see that on the 1.7 roadmap and was curious if there is any backround with it.  I've started work with "Pull Printing" and this sounds very similar.  Pull Printing being that you print to a nebulous print queue in the sky and then authenticate to any printer and it Pulls your print job to it.  Similar to this STR at all?
