A naming scheme might indeed be useful for basic cases;  this could be linked to the "Manifest API" Christopher talked about. With such an API, manifests would not be required. 

A naming scheme / API cannot be the only option though, since there'll be issues around such cases as:

* Load balancing (mid-stream failure of a server, redirection to the other)  
* Encoding issues (discontinuities in the chain/scheme)
* Dynamic insertion of unrelated chunks (e.g. for pre/mid/postroll advertising)
