I like your point here .. it's difficult to make such a comparision,
since yacast.fr choosed to stream like that. Why did they choose to
stream like that? That's beyond me, since Radio France has a budjet of
The point of this comparision was to show why is Radio France doing and
paying for something like this? Me, with cheap computers which were
had no more value (well, they can't run Windows XP) could be used to do
streaming and reliable streaming.
This is only possible because of the open source work ... which shows
that when creative thought is not stamped out by bureaucratic ineptitude
or/and corruption, it can achieve the "impossible".
I do feel that Radio France, since it is a public service, does have the
duty not to waste money. This was also a point of my "comparision".
