alt Hacker NewsYa, the word "transplants" here seems to mean something very different than you're interpreting it as.
This isn't a hospital procedure like an organ transplant. It's material placed into the recipients colon through an enema, nasogastric tube or possibly even just taking some pills.
So it might range from done at home to done during a 30 minute visit to a clinic.
I know it's nothing on the scale of an organ transplant, but (other than pills) those things would still lead to the patients being at the hospital. And with frequent enough visits to a hospital, you would probably eat at least some meals there. That's all I meant (and said).
