Software to silently shadow RDS session via command line in Server 2012?

No.. I wasn't able to find it out. I have spoken with Microsoft Product group with the help of our TAM and they may be incorporating this feature in the future products of SCCM. They haven't confirmed but it may happen. Also, I have provided the same feature request in MS Connect. If interested, please vote for this feature.
