Would you consider a DIY solution?

Run myth in the usual way and have a background process that
periodically moves some files to another fs (local or remote)
and replaces a symlink in their place. Myth will have no
knowledge of this.

You now have full control on how to distribute the data, you
may even decide to keep more than one copy if you have the space
(in different places naturally) and you can reorganise it all
as your storage situation changes (e.g. migrate some of your
FSs to larger disks).
