SFR (guest single file restore) is not going to be included in VSC 5.0. We decided that rather than port a feature that needs a major 'facelift' from the C# client to the new web client, we'd live with a release or two without SFR so that we can redesign it. SFR supporting both Windows and Linux will make a comeback in a future release of VSC ... stay tuned.
we ran into the reduced funactionality trap and also because we use linked mode (sperate VSC instances accross vcenters) we couldnt use VSC 5.0 we stuck with 4.2.1p1 (yes there is a p1 release) and use the c# client still. we need to use the c# client for update manager and SRM so its no bother really. shame VSC 5.0 wasnt anywhere near what it was hyped up to be! maybe VSC 5.1 will be?
