Yes, we want to eventually replace all existing examples and utilities
using USRP/USRP2 with the UHD driver. There are quite a few of these
programs to modify and get properly working.
So... I'm hoping that people will offer to help with the transition
process. If you do rework some of the existing functions and examples
with UHD, we would really appreciate you contributing it back to the
project, which will significantly speed up the work.
Thanks!
