I'm one of the inventors of BiDiB. To give some clarification:
railcom is one way (not the only one) to get data back from the loco to command station and/or pc. BiDiB is independant from railcom.
is a hardware/software protocol suitable for the transport of all this upcoming new data. In addition, this protocol offers for the first time in the model railway history a secured transport of occupancy data. Security and reliability is a major request on larger layouts. BiDiB is open to all and not restricted to one vendor. BiDiB was designed with the requirements of layouts in mind - built out of practice.
BiDiB was presented to a group of manufacturers in Berlin and was considered as a candidate for a new standard bus. Of course, a lot of implementation work is still to be done and BiDiB devices are currently not available of the shelf (or GA, as Rob said)
There are two BODs commercially available: one is Blücher GBM, the other is RC-Link. Both have committed to convert the host interface to BiDiB, but again, this takes time and needs resources.
My GBM16 (http://www.opendcc.de
) is the first test implementation of BiDiB - up to now, the flat model is up an running. The hierarchical model is under development.
