The disadvantage:
You have only the "most" german Astra and only digital channels. 
More are not possible because your single cable does not have enough bandwith.

Recently i saw at Conrad a 
"Digitales Einkabelsystem" smart GP31-D 940351 EUR169,--
which seems to be similar to disicon but works with any LNB...

(Technisat solution costs only 150EUR and "includes" the LNB!)

The base GP31-D device supports only german TV-radio channels
on 22 Transponders
(65,67,68,71,73,75,77,79,81,83,85,87,89,104,106,108,110,112,114,116,118,120) 
and a few non-german but works with any receiver!
It uses only the hi-Band (so no TDSL is possible)

The GP31-D can be extended to convert further transponders.


Another device seems to be Schwaiger EKF1100, but they
are talking only about 2 receivers...that's not what we want ;-)

?? i thought they where mixing the digital signals into lower
bands.

AFAIK a Disicon can feed any(!) amount of receivers.
You just need additional amplifiers.
If each receiver has it's own LFO the max. number of receivers
would be limited, or?

If i built a new house in would not use such single cable solutions.
Those single cable solution are good for old houses.
