No, there's no provision for that. A single process has to "own" the USB
device handle, and relevant internal UHD structures.

Can both processes communicate with the device concurrently? I noted that the make() call to multi_usrp returns a shared pointer, so I was wondering if (as a result) you can have multiple processes access the same physical device (with the same device arguments).
