only 400k, in peak(!)

AFAIK Telekom calculates with at least a 1:30 bandwith ratio!
(Remember: there are MANY guys who bought "flaterate" because
they only saw the low price per MB, but they pay per month 
much more than they actually uses. And: Telekom is "sponsoring"
T-Online a lot!)

But would 300.000 E/month do it for one transponder?
I don't know the prices.


I think tiscali is trying to use "IP multicasting",
so one paket may be usable for more than one receipient.
Else it would be difficult to realize....
(I don't understand, why they do not offer NNTP (usenet) too, 
which would be ideal for multicasting...)

upto  400 kbps Download
upto  130 kbps Upload





"Tiscali start" (for germany)
 420 E Installation (should not be done DIYS because the uplink it must be 
       adjusted very exact.)
  79 E Setup (once) 
1099 E Hardware
92 E month for at least 12 Month(upto 24)

"Always on"

+ 15...35MB Webspace+5..15 mailboxes

"Tiscali LN"
for "up to 5 computers" 100MB webspace etc.

Does Telekom do/did?
Remember what happend to the ISDN-Flatrate.


>Do they guarantee a minimum bandwidth?

Does Telekom do it for private users?
There are only few providers who "guarantee"
a minimum bandwith, and that is real very expensive.
 

>Do they support Linux?

They seems to use Gilat Satellite Networks Ltd. ("Gilat VSAT") technique
using 
Eutelsat Eurobird (28.5 Grad Ost) with a 
75cm eliptic diameter (60 x 90cm) dish and a 
special Transceiver "TiscaliSat".

The TiscaliSat "modem" is connected via USB
or Ethernet to a W*-PC. Linux and Mac are planned for 2002...?
Only IE and NS seems to be usable, 
only HTTP,FTP,ASP?(No POP3?). 
Bandwidth eating protocolls like "filesharing" may be forbitten/blocked. 
AFAIR: No "servers" are allowed on the PC.
No "realtime" applications (due to the long RTT) makes sense.



-----------------------------

I think 1300 Euro for the first year + 1500 Euro startup cost is a
lot of money for a very limited service...
