There are two ways. The old way provides the full path to the DLL to the
LoadLibraryW call. VLC does that currently. The newer way calls a dedicated
Win32 API function that register an extra DLL path. I forget the exact name
and it requires Windows XP SP2 or something, which is why VLC did not use
it.

VLC 1.2 will drop support for Win2k, so then we have an opportunity to fix
this mess.

Currently, you cannot do that. That is why VLC plugins are all statically
linked on Windows until now.
