Yes; it does not have to reside on the local system (best that it does) as long as it is located relative to either a permanently mapped drive, or registered on a UNC-based location.

You can register the OCX either using REGSVR32, or by making a call to the Win32 API library that will invoke the OCX/DLL self-registration code (there's an example of how to do this in the FAQ.) Whenever the location of the OCX/DLL changes, or a new version is put in place, the file should be re-registered on each system affected.
