Multisource connection in IDT 4.1

I will appreciate if someone response fast for these
solution questions.

Is that possible that “IDT 4.1” connect to SSAS cubes as
well as BW cubes in one Multisource connection? 

Can we connect two different OLAP cubes from two different
source same time in one IDT 4.1 universe like BW and infoprovider and SSAS cubes?

Is IDT 4.1 universe can handle more than two cubes same time from one source system?

Thanks
