I think this idea has merit, but I think the title is all wrong. Once you start talking about group cooking, you move away from alcohol. I love my little alcohol stove, but when I hike with someone else, it just makes more sense to use a canister stove. Once we hike with a big group, or for a long time, it makes sense to use a Jetboil or white gas. Likewise with melting snow for water.
On the other hand, there are places where dealing with a canister stove is difficult (it may be hard to take them on an airplane or buy a canister at your destination). So, there is that.
The greatest value I see of this setup is for anglers who camp in areas where wood burning is not allowed. Typically, you can't guarantee that you will catch a fish. So, you want a stove setup that will allow you to boil water for dinner and breakfast, as well as provide a way to cook some fish (if you are that lucky). I could easily see bringing a Caldera Cone (for boiling water) along with this (one ounce) stand and a flat, aluminum (or titanium) fry pan. Off the top of my head, I think that would be the lightest setup you can have for those conditions.
