I think what they are referring to is the effect of increasing the number
of Beacons on a single channel.  For example, simulations at the Royal
Institute of Technology in Stockholm appear to indicate that with 5 VAPs,
approximately 20% of the AP's capacity will be used for Beacons; with 10
VAPs, 32% of capacity is used.  So there are practical limits to how many
VAPs can be Beacon'd, regardless of how many a vendor might support.
