At one stage I had a beta in testing, but it turned out that it was causing problems about 3% of the time. Since I am the type of person that will not accept a less stable firmware in order to introduce new features, I decided not to release the update. The product works as originally intended.
I have not given up on enhancing the wgt634u based IceBox, but I don't have time right now. It would take a few days of full-time work and given the current workload, I'm unlikely to have those few days for at least 6-9 months. On the plus side, all the source code to the firmware and tools has been released, so any reasonably skilled person can step up to the challenge.
