This is interesting, however note that wine often runs proprietary applications that we cannot put into the repositories. Alot of the stuff run in wine are things that come with a box and a CD that you get in a store.
For those that are free (libre) this is a possibility. However keep in mind that wine is still in the beta phase, and is in no way a finished or stable product. Heck they break stuff that works quite often, though this seems to be happening at a reduced pace these days. Yey regression testing :D
