Depending on the number of satellites you want to receive and which ones, it might be possible to set up a fixed dish with a multi-lnb bracket. This could typically give you up to 4 satellites. I have a 90cm dish with a multi-lnb bracket and 4 quad LNBs pointing at 28.2e, 23.5e, 19.2e and 13e. This allows each dreambox connected to all the LNBs through its own diseqc switch to select satellite/channel independently. In your case it would require 4 dual lnbs mounted on a multi-bracket if you want to feed 2 x dreamboxes. Then each can independently select the satellite/channel as it is done through 2 x diseqc switches, one per dreambox. It also has the advantage if instant satellite switching as you dont have to wait for a motor to move the dish. Downside is the satellites have to be within 20 degress of each other and the closest they can be to each other is about 3 degrees, otherwise the LNBs jam against each other. In my case I had to shave the 23.5 and 19.2 LNBs slightly to get them closer together. You also need a bit of a bigger dish as the all the LNBs are not perfectly alligned and there is some signal loss because of this slight offset.
