We actually have a vibease, but it has a level of encryption built-in that's slowing us down.
I seem to recall that the Hum is also going to be BLE, but I can't find any references right now. We need some way to control the devices, so we really need some sort of Bluetooth or USB interface on the device.
Most of the devices we've worked with use BLE for short range communication and a phone app acts as a proxy for longer range control.
We've recently added support for a long discontinued USB vibrator, and we've got a couple more planned.
