I am curious to what happens behind the scenes.
*Does Lightroom create a smart preview (partially developed, compressed file) that Lightroom Mobile then process on the fly for rendering?

*Does Lightroom Mobile read/write the regular .lrcat catalog file, or a local copy/light version? Regardless, how are the files maintained and synced? Is it possible to keep the lrcat on a storage resource (such as a NAS), accessing it both from Lightroom and Lightroom mobile?
*If you edit the raw files in regular Lightroom, then open the catalog in Lightroom Mobile, will you get to see things that could not have been seen if you opened the file directly in Lightroom Mobile (in other words, does LM show the essence of what was done in L development?)
Yes, it seems that this is a thing only for subscribers and iPad users. I am none of those.
Nope...only Flag at this point. Rank and Label due in the future...this is really a 1.0 effort so a lot of stuff ain't there yet...
Bummer. I use the star rating actively, and being able to tag those things in the couch (or on the bus) could be a nice feature.
Reading the blog post, it seems that (part of) your lrcat is uploaded to the cloud, along with (reduced size) smart previews, so that the edits and image data can be accessed wherever you have an internet connection. Presumably, the local lrcat on your computer will be updated whenever you start Lightroom.
