Q: Will this work the same as a Yamaha md-bt01?

Yes, but much better. I own both. I've found the WIDI Master to have a better range and stronger signal than the Yamaha unit. It can also do something the BT01 can't. You can connect two WIDI Masters together without the need for a computer or mobile device. Just plug and go. It's a fantastic product.

Q: Will this with qrs pianomation systems?

I hooked it up to a Pianomation system, but it is a little tight fit. Works good though. You have to hook up the midi out as WIDI Master gets its power from MIDI out.

Q: Do I need two of these to connect two devices

Maybe. I use one of mine to connect to MainStage on my Mac and with this scenario, I only need one since the computer has Bluetooth.. Connecting two keyboards together requires two, one WIDI Master for each keyboard.
