single vs multiple hostapd instances

[Bill Hegardt]

On a dual band platform with 2 radios, is there a functional difference between running a single instance of hostapd for both radios vs
separate instances of hostapd?  For example, does a single instance of hostapd have an advantage when a station roams between the radios and
handle the roam more efficiently?

I would assume there is no good reason to run separate instances. True?

Thanks
