We reuse them for personal use in the "proper" brewery, but you need to take care when you remove the plugs, and they don't last for that many brews.
It's not something I'd rely on for home use. I'm not a massive fan of them for anything other than racking bright beer into either to be honest. Without a decent way of dispense, you're risking oxidisation if you don't drink it within a couple of days.
