In germany I have payed for a Redunant E3 at UUnet around 
10.000 Euro/month and then the traffic :-/ around 25.000 Euro/month. 

Oh yes, In Germany You get the Acces realy cheap, 
but you pay for the traffic !

Yes, but you can only use 4 Channels paralel of the 19.

The 54 MBit are only Theory !
Practical you can get around 40 MBit for each channel.

So if I install for example 4 Channels in Casablance I 
have around 40% of all resources there !

But, if I calculate with 5-6 E3-Links and 42.000 Euro per Link, 
I will necer earn money with it !

I have friend in Marocco for more then 23 years, and I have 
done there very much, NOW the are thinkin, I can do ALL !!! 

Generaly right, but I need enough time for learning

Curently I am preparing only a study about this project and 
its possibility. I think realy it can be done...

Regenerativ Energies are sibsidized (I was thinking to install the 
WaveLAN Relays with SolarPower)

It depends, because

1)  If I have only a NetworkCenter (4 x OC-3) for my CyberCenter 
    project, I need only RadioBridges which supports E1, E2 and 
    E3 and OC-3

2)  If I support paralel to 1) commercial Users (End and ISP), I 
    need a bigger Backbone like 2 x 1 GBit which mean, I need 
    GBit RadioBridges maybe up to 1,8 GBit too. 
    
    <http://www.wirelesguys.com/>
    
    The price is realy heavy (around 27.000 US$ each ) and they 
    support not more the 20km and you need many Briges...
 
    What I need is a study about installing wired ! 
    Dont know the price for the special cable, the Repeaters, ...

I was thinking about minimum two independant and 100% redunant ISP's. 
OK, I have already 26 Server prepared, but it is only for the 
CyberCenter and can support up to 100.000 customers . 

Bigger Backbone need bigger Servers...
So 100 MBit FullDuplex will not enough.

You mean via Satelit ?
I have read an Documentation that one Satelit Link can support 
up to 50 MBit. Is this right ?

But there are already concurence:  <http://www.directsky.net/>

OK, this is logicaly

>(Or 60000ft, to stay clear of the airliner etc traffic.)

I can use the Proxim Tsunami MP.11a which sopports with the 
Outdoor Router Software upgrade Traffic Shaping from 64 kBit 
to some MBit (do not know exactly)
