You can distribute the python part via the official repository, then
during the plugin start up it could check for the presence of the
binaries - if not found, it would ask the user whether to download the
binaries for their platform (if available) from your website. For
example, Crayfish plugin [1] does that, providing binaries for windows
32-bit / 64-bit.

It is also possible to set up your own repository (a matter of having
one XML file with metadata about the available plugins) and ship
everything packaged - the downside is that users would first need to
manually add your repository to QGIS. With this approach, the downside
is that potential users will not likely discover your plugin (unless
explicitly instructed to add your third-party repository).
