One possible way to free the user interface dependency on one single API
is to separate the user interface code from the DSP code completely
(different processes). The communication could be done using Internet
sockets and a simple client-server protocol. With this approach, user
interface developpers need only to follow the protocol specifications and
DSP developpers don't have to worry about user interface issues. Another 
advantage is that the DSP code could even run on a separate machine.

What do you think, Leif?
