Yes , I understand, there probably is no simple answer. 
I normally make applications for Microsoft Windows and don't know much about Linux.
If you make a virtual sound card in Windows you have a solution that covers all applications.
I assume it must be possible to do something similar in Linux. 

I want to use the solution in Meego, Android, and Google Chrome OS - if possible. 
I do not know what applications the end user is going to use, and I might not need 
multichannel audio support for all the operating systems. All the operating systems 
are based on Linux so they must have something in common regarding the audio chain
(such as ALSA) where I can plug our DSP code in.
