what do you want to do with wine on ppc?
Guess? Like play my favorite MMORPG game for example, run Windows apps and games...you know...that stuff...
By the way do not go through that route of...if you wants windows stuff using Windows....road...you know as well as I do..or maybe you do not know...that WINE actually helps and not hurts. For example, I am download crossover...if crossover works 100% better than WINE and it can run 60% of the applications I want in Windows in Linux and my favourite linux Distro....I would drop windows in a heart beat and go for Linux and I will be an official 100% linux user. So now Linux have a new customer...why? I do not have to deal with spyware, adware, hacking, viruses and paying fortune for applications...I can use linux free applications and my favorite games or applications that are free and really free in windows like MMORPG games and so on...I can enjoy them in Linux.
I do not have to deal with horrible file system of Windows...worry about new policy of Microsoft and be stuck with horrible user interface of windows 8 and deal with constant windows upgrade...and purchases because Microsoft no longer supports OS in favor of the new one....
By giving people the freedom to use their favorite apps that do not exist in other platforms through WINE or crossover...you are liberating people and giving them choices instead of being forced to be stuck in Windows..and then these unknown OS will be more known and more users will come to them because they know if they move platforms they STILL CAN USE their favorite apps and games....
Same concept as Amiga Clone actually could have helped old classic Amiga...
