I hardly think this has been taken over by farms at this point. The dev mentioned that he has hundreds of connections and this thread has been seen by over 1000 people, so it's not unusual that so many individuals have started mining this. It's a popular launch. When the network hashrate reaches 1 GH/s then you can complain about farms. Until then it's still possible to find blocks even with an average PC.
It's probably a mixture of everything, but your guess is as good as mine.
IP clusters point to some concentration in the hands of mid-sized farms,
then there are certainly many little guys because of the popularity,
and last but not least there is the distinct possibility that some GPU dev has already created a miner and is probably hashing away at 20 MH/s on a single GTX 1080 Ti (my estimation).
If you exist, GPU dev, I salute you!
But all that doesn't bother me, what is more important is the connection issue and that all those in-wallet-CPU miners of the CPU-farms are eating away connectivity.
I'm eager to find a solution to that.
