It's worth noting that newer Ubiquity APs no longer support Zero Handoff. Part of the problem was that all the APs needed to be on the same channel, which caused co-channel interference under heavy usage; there was a significant performance impact. (Also, I believe that chipset in the newer Unifi models just don't support it.)
Without it, clients can still roam between APs, but you'll notice ~1 second of packet drops each time your client roams to a new AP. It won't drop a VoIP call, but you'll notice a moment of silence when it happens.
The future is 802.11r/k/v, which will allow clients to roam themselves quickly between participating BSSIDs without needing to renegotiate the connection each time (as opposed to relying on pure AP-based hacks).
