I personally think what you are trying to do is pretty nasty.

Have you read the subversion book and in particular the parts about path based authorisation?

Perhaps noone understood because you asked how to _do_ something specific (which people are cautioning you against) without asking how you can achieve what you _need_ in a way that subversion is designed for and supports? Having said that...

I think you can do all that by creating your (sub)hierarchy within the 'x' repository and using path based authorisation. The most specific path is used for auth so subproject 'z' can have its own auth which overrides that given to 'x'.

Unless this conflicts some specific requirement(s) of RedMine that you have not mentioned? What source control does RedMine normally work with? Perhaps you would be better off using that?

One IMHO very good argument was mentioned and you ignored it: you would not dream of messing around inside the file-system location of e.g. PostgreSQL database data files yet that is exactly what you are proposing to do with the subversion system. Are you proposing only to use File:\\ repo access?

As also mentioned, implementing what you are asking for may cause unnecessary implementation constraints for the project in the future by implicitly supporting a possibly unique use case?

Finally I am wondering: how are you proposing to provide access to the repositories? I shudder to think of the sort of apache config that would be required to serve a repo from inside another repos folder... Subversion supports paths inside repositories and grouping of repos using ParentPaths, all with authorisation mechanisms that satisfy most existing users.
