I don't know how it relates to Zope.
There's FFServer (http://ffmpeg.sf.net) - powerful streaming solution.
Or you may be interested in www.MMManager.org - Multimedia manager for
Zope.

[Zope-dev] Streaming large files

[Thilo Staebler]

hi!
I have to stream large mpeg-files over http with range support. this 
works quite nice until the client seeks in the (media)player and the 
files aren't to large, because zope caches the whole file...
...so each seek means streaming the whole file from the requested 
position till end *g*
-> my RESPONSE object doesn't even know, that the player has seeked e.g. 
back to the beginning...
is there a way to bypass the zope caching? and how do I know if the 
player has disconnected, so I can stop streaming?

thanks in advance
thilo

[Zope-dev] Re: AccessControl Problems on Mac OSX

[Casey Duncan]

It looks like this bug was closed due to lack of feedback from the
original poster. I would suggest opening a new collector issue and
reference that one if you think it is the same issue (it certainly
appears to be on the surface).

The collector issue would stand a much better chance of being acted on
if you also submit a patch with a cooresponding unittest that fails on
Mac OS X with the current implementation.
