@pociej: th IR-Booster will be available later. It only transmits data so i can not be used as receiver. The only way to extend the range of the keyboard would be to relocate the IR sensor of the aquaero to another place. It is only soldered with three points to the board and can be accessed easily.

@ohms: the poweradjust has two aquabus connectors so you can connect the second controller to the first one. Before you connect them to the aquaero you must change the aquabus of ID of one controller. To do so connect one of them via USB, run the current aquasuite and change the ID from 50 to 51 for example. Save the settings into the device. This step is necessary because otherwise the aquaero will not be able to differ between both controllers.
