You don't need the mod border-element command in order for a router to have
CUBE turned on.  Simply having the UC license and allowing voip to voip
connections gets you CUBE functionality.  The mode border-element command
does have it's purposes, for example CUBE HA, and Local Transcoding
Interface (LTI).

1) Honor based licensing, and you can police it yourself with commands on
your dial peers (it's part of the CAC functions of CUBE)
2) First you start with hardware, and then you look at licensing.  So, if
my router can do 100 Sessions, but I only bought 50, then the limit is 50.
3) Correct.  E.g., A single employee makes a single PSTN call from their
single IP Phone. That's two VoIP legs on the CUBE, but only one CUBE
session.
