I'm running the latest BlackHole but I'm sure that there are heaps of things that an experienced person for these boxes can do to make it really usable. I'm not wedded to BH, so if you think that Vix (or any other interface) is better and can justify that, then I'm open to change
If anyone is experienced in setting these boxes up so that it is wife-friendly fancies coming round and getting it really working well in a user-friendly manner, then I'd be happy to provide a box of beers
PM me if you are interested.
