Hi,
Here is the message I posted Friday... but everybody didn't receive it.

I tested the miniSapserver 0.3.4 found here :
http://download.videolan.org/pub/videolan/miniSAPserver/
This version has some bugs.
DO NOT USE IT
Problem was in the announcement interval.

I corrected and now the intervalley of dispatch is 30 seconds (fixed).
You can find sources here : 
http://exp-videos.univ-paris13.fr/src/minisapserver-0.3.4b.tar.gz

I'm under Linux. Commands to install :
#./configure (--prefix=...)
# make && make install
# ./minisapserver -d -c sap.cfg

sap.cfg exemple with 2 announces :
[global]
sap_delay=55
sap_ttl=255
[program]
name=Video SD 352x264 - 35 ans P13 - IPv4
user=videolan
machine=exp-videos.univ-paris13.fr
site=http://exp-videos.univ-paris13.fr
address=224.5.43.1
port=1234
playlist_group=University Paris 13
program_ttl=255
[program]
name=Video SD 352x264 - 35 ans P13 - IPv6
user=videolan

I created a blog which lists all information
I shall give you the url as soon as it will be made
