multiple audio devices

i'm sure it was asked for already but i don't see it on the first pages so..

wouldn't it be a good idea to add a way to use several audio interfaces/devices?

yes, i know there is a shim: asio4all. however, my audio interface allows me to play with 32 and even 16 samples buffer, while asio4all has 64 samples min. and when it's about guitar the less delay is, the better it is. don't forget all these further vst effects that may very well add to a final delay, so smaller delay with a usb port is always a profit.

besides, i guess using the interface directly through its own driver is always better. and i think it shouldn't be a hell of changes in the code. i think it would be much better than using a 3rd party software that limits hardware features.
