[LUNI] Multimedia open source solutions

[Stefmit]

Hi,

I am faced with a chellenge which - I believe - could be addressed using Linux 
and one of the multimedia capabilities to be found in open source. 
Unfortunately I am not very good at open source multimedia options, so I am 
seeking advice from those of you having done something like this (and willing 
to share, of course ;))

Requirements: multimedia streaming (flash content, streaming video, slides, 
etc.) from a central location to remotely placed LCD monitors (large size >= 
42"). The content should be transferable at different times than when it is 
supposed to be played, because of already overloaded WAN links ==> end points 
have to have the capability of storing and then schedule/cron-playing content 
on the LCDs.

The approach I envision in resolving this is by using small factor PCs, to be 
used to connect to the monitors (if multiple LCDs - I wonder if I could use 
multi-head card, with a solution capable of playing different content on 
different LCDs).

Does anybody have any recommendations for software and/or a 
multimedia-oriented distribution, and/or additional advice(s) on how to 
tackle a problem like the one described?

TIA,
-- Stef
