If this is a serious problem, what about simply packaging Wine in 6-12 oz bottles? Single serve glass wine. This looks like a really over engineered solution to a rather simple problem.
Now you could argue that maybe they are going to get good wine and make good W-cups. But people are making "good" boxed wines now too.
Sticking wifi on it just seems like a gimmick.
There's not much of a demand.
I guess the main costs for wine producers are not the bottle nor the wine, so there would be little price differentiation (which is essential) and moving larger quantities of 1 format is better than moving smaller quantities of 2. A lot of producers struggle as it is, so supporting another format is hard. Still, if a cartel of producers agreed on a secondary format, pooled costs and launched a "tasting" line, maybe it would be viable.
