Subject: Re: [PATCH] filter on session age

Hi Stephan, Kees--

It should NOT be done this way.... the Stream API (see stream_api.h)
has functions to access data for a given Session/Stream. It will
be used going forward -- direct use of stream.h has been removed
from all other areas of the code.

This is being done to have a well defined interface to Stream to
ease integration with a new streaming engine when it is ready.

Cheers.
