Correct, it should be quite easy to change usbredirserver to act as a client (please copy
the .c file to usbredirclient.c and modify that if you want to go that way, and then to
make qemu listen instead of connect, then you no longer need to launch the usbredir server
first.

In the upcoming qemu-1.5 it will be possible to dynamically add chardevs.

No, I'm afraid not.
