Alternatively is ULA proposing an RL-10 replacement to be used in the SLS's exploration upper stage?

Hello Mr. Bruno, Thanks for doing this AMA for Space Enthusiasts everywhere.

Has there been any ongoing efforts by ULA to develop propellant depots since the 2008 study? Would ULA consider taking on the cost and risk of developing this tech in order to foster growth of the commercial market or opening up mission options for government agencies? (If you build it they will come?)

Is there any interest or plans to look at building ULA's Integrated Vehicle Fluids technology into the EUS?

How does the LDSD compare to rigid heatshields for accuracy and control through that phase of descent?
