RDS License server - Device/User based CALs and Collection

Hi All

My understanding is that licensing mode is selected per Collection.

1.  Can a single RDS license server manage both User and Device licenses? 

2.  I think MS Office products are licensed per device, therefore I assume I group all Office products within a single container and set its licensing mode to Device?

We also support W2K3/8-32bit desktops via creating a published RDP file which effectively RDCs into W2K3/8 servers running Terminal Services (for backward compatibility of certain 16-bit apps).

Will two client licenses will be consumed per user, one for RDS 2012R2 and one for the target W2k3 or W2K8 32-bit server?

Any pointers more than welcome.

Cheers
