Option to host CB on path other than root

Unless I missed something, CB expects to be hosted on a root path of some (sub)domain.
I found no configuration option for setting a base path, and when embedded as suggested with a path other than / the embedding does not work (tries to load /chatterbox.html for example instead of /some/path/chatterbox.html, and of course why would it without any configuration.)

I would like to be able to specify a basepath for chatterbox.html, assets, etc.

The alternative is to host it under a root path, potentially under an extra subdomain.

Cheers
