Teledesic's satellites visibility

Hi SeeSat-ers,

I recently got a message with the following question:

>I am a computer science & engineering student, unskilled in the world
>of satellite reflections. I read your excellent introductory paper on
>Artifical Satellite Observing on the net, and I figured you might be
>able to answer this question.  (If you're busy, please ignore it.)
>You have surely heard of the Teledesic project. A total of 840
>satellites will be launched and placed in low earth orbits (700 km)
>My question is simple: Will those satellites be visible to the naked
>eye even during daylight?
>(And how many of them can be seen at once from any given point on the
>earth surface?  More than one I assume.)

The author of the message ( -he's not on SeeSat-L)
correctly guessed I'm busy right now. I figured perhaps someone on SeeSat-L
has already taken a look at this problem and can share his results with us,
as I think it may be interesting to all observers.

Also, does anyone know whether Teledesic's project is 'real' and not just a
marketing hoax ?
