Would cloud-based trophies work?

There are sites like RetroAchievements that add achievements to retro games that don't have them, as well as saving users' achievements to their online profile automatically. Since most PS3 games already have achievements built in, it would be even easier.

Would it be feasible to add a separate RPCN profile that tracks trophies? Even if it doesn't have any kind of anti-cheat it would be fun to save trophies to the cloud like on PSN and trusting people through the classic honor system would work well enough in small communities like this.

What do you think?

That would be great in my opinion :3

Adding a separate RPCN profile to track trophies for PS3 games could be feasible, especially if it is implemented as a community-driven system relying on the honor system.

I think having a RPCN keep track of trophies would be pretty cool. It is possible that RetroAchievement support could be added to RPCS3 at some point.
