Excellent point Jim. All services' grounds (AC, telephone, television,
internet and ham shack cable entry point & ham tower) must be bonded to a
single-point ground system. There's no limit on number of ground rods as long
as they're bonded (i.e. tied to the same grounding system). 8 foot ground rods
need to be within 16 ft of each other, but can be closer if needed to shorten
cable run to each service ground connection.
Couple more good references for grounding and bonding standards from Motorola &
Harris:

The only "issues" that arise is failing to bond them together. The
simple rule -- you can have as many earth electrodes as you like, but
they MUST be bonded together, and to the power system safety ground bus
at the service entrance.
