We've got about five licenses and a remote 7960's v6.3 running over
dsl working just fine. The average user cannot tell the difference
between 711 and 729. Installation was easy and straight forward, 
although you'll find comments in the archives that 729 installation
requires a non-scsi drive on the * box.

In some cases, you might require two licenses even though you might
have only a single 729 phone. Think about VM, etc. Error on the side
of too many.

Can't comment on support; never needed any.
