You'll need to log into the server anyway in this case: you cannot
create new (sub)repositories on a server without a login.
Your options are:
* the share extension (sort of in-Mercurial symlinks between .hg folders)
* let hgweb export the same repository under several different paths
Those three ways will let clients clone subrepos using trivial subrepo
paths and there will only be one repo on the server.

Yes, that is an interesting idea and I've even proposed in the past that
the trivial path is always used first with "real" path from .hgsub used
as a fallback in case the trivial path does not work. This was last
mentioned here in a greater context of using a local cache for a clone:
