I was also worried about the noise the rig makes from my neighbours point of view, as well as the weight of it being in an upstairs room, 150kg.
Also, just found a vendor for these rigs online that's UK based. It'll be worth making contact with them, as I'd assume they have a right setup for eemo purposes somewhere?

On the issue of software, there are 2 programs that I've read about. It doesn't look like either are free...one's definitely subscription based.
