I haven't heard about those, but I'm guessing the two will never meet? The big problem (from my perspective) is that the cool stuff has been done on the Java side, including all the huge player communities. Even if Microsoft replicates that (via purchase) on the C++ platform, will it ever really be the same?
I know there is an open-source effort to create a PE server (one of my friends runs one of these servers that's in the top-10). But, when I go to play there, it's just missing too many of the features to pull me in. And, since they reverse-engineered the server, they'll always be playing compatibility catch-up unless Microsoft changes their vision.
I'd love to see the Java version get some new-life or for Microsoft to make the C++ version more like the Java version... but I think it's a numbers thing. There are simply a bazillion more people with mobile devices than PCs setup to run Minecraft. And, that's not including the consoles as they go the direction of tying in with mobile (further boosting that platform).
