[linux-audio-dev] Re: linux-audio-dev Digest, Vol 19, Issue 33

Andres, and all,

A very interesting idea, though here in West Africa, the main limitation
in Linux adoption is not a lack of modem support, it is more to do with
a lack of knowledge about Linux and open source, and too many aid and
commercial organizations only touting or buying proprietary product.
Here there are very few computers at home and even fewer people who can
afford the incredibly expensive phone costs, that is the main reason
that few modems are used here. Those who can, can afford hardware modems
that supports Linux, as the monthly phone bill will well exceed. I was
at an internet cafe recently, who had to shut-down because in one month
their phone bill was over $350, twice their revenue. So, I think that
though this is a solid idea, and that it might have application in some
developing countries, here in West Africa modems and phone lines are the
last choice due to their expense.
