I am speaking of docking access. SpaceX is working on a private-sector crewed vehicle similar to the CEV and Rocketplane Kistler is also considering a manned capability for their reusable booster.
Actually NASA has been making squawks to that effect, apparently they would love a US based alternative to Russian resupply of the ISS during the end of Shuttle Flights and the begging of CEV flights.
The new NASA administrator has made several speeches about NASA’s willingness to utilize and support civilian infrastructure and even co development of hardware.
