[pluggo] Apps compatible with 8 outputs-pluggos on Macintosh?

Hello,

I want to build Pluggo plug-ins with eight outputs. I know it is  
possible to split the outputs on several channels using the Pluggo  
busses and several receiving plug-ins. However I would like to know  
whether there is any Macintosh supporting surruond plug-ins on a  
single channel because I want simpler configurations? My last  
attempts with Logic Pro 8 and Pro Tools LE 7.1 suggests these  
application do not support such plug-ins. What about Digital  
Performer, Cubase, Nuendo?

Thank you in advance.
