From an out-of-process COM object (LocalServer32) can I determine the client process that requested the creation of the object? - to be specific I need to get hold of the client processes command line.

This question arrises because (due to poor standardisation, implementation and support) the potential 3rd party clients of the object have a variety of idiosyncracies which the object needs to workaround.

To do this the object needs to be able to identify its current client.

Extending the interface of the COM object so that the client can identify itself is unfortunately not possible ... or to be more precise the interface can be extended but I won't be able to get the clients to call the extension.
