Replay Cache

OpenPHT has an option related to the Cache Size.

It seems like this cache is only a forward cache.
For Replay (step back 5/10/etc seconds), it seems like OpenPHT has to rerequest the content from the server and there is a pretty long delay just to go back a few seconds (when playing a video from a remote server).

Is there a way for the cache to include some of the last x seconds so that you can step back and hear/see something you just missed without having to wait to buffer?

As an aside, if this is not possible on OpenPHT, does anyone know if any of the clients have this?
