My previous comments are about the "dream" of share a CI_module between two
DVB
cards (one at least having a CI connector). I say "dream" as it need a
hardware
transformation of the cards, which isn't easy to do to someone not
customary and
brave :-).

The Nova_CI have a connector where you can connect a CI_module (wich AFAIK,
it's
sold apart from the card). If you have two cards and each one have connected a
CI_Module, of course that you can use any CAM with any card.

Yes. But with only this, you need to swap cables if you want to pick the other
satellite!.

To avoid confusions:

.- I talk of one twin_LNB as a "head" that allow the simultaneous use of two 
   receivers on the same satellite. Two twin_LNBs and two Diseqc switchs
   allow two receivers to pick any of two satellites.

.- On the market there are "blocks" that allow the pick of two satellites
   with one dish (ie, 19.2E and 13E). This blocks have an integrated Diseqc
   switch, for use with a unique receiver; its are easy to install, but
specific
   to one dish and satellite pair; can cost more that two LNBs and one Diseq
   switch.

.- Finally, maybe there are "twin two satellites blocks", but again I think
that
   the cost will be more that the individual parts.
