I am surprised about your concerns on OpenSplice DDS adoption. OpenSplice DDS is today deployed on over several mission and business critical systems such as Naval Combat Management Systems, Military Vehicles, Air Traffic Control and Management, Metro, to High Frequency Auto-Trading. Just to give you another bit of info that should give you reassure you w.r.t. the adoption of the technology, the OMG DDS standard (the standard implemented by OpenSplice DDS) has been recommended by EUROCAE to exchange flight data plans across centers pan-european.
Let me know if you have any further questions either on the adoption or the technology.
