You can run them without a laptop & controller by using the connection kit but it looks like only mono right now. The DMI-2 controller is AC powered so no easy, lightweight field use for now. The DMI-2 handles two channels and has an ID selector on the back sort of like SCSI devices so it may be possible to chain together several units, I haven't read that far yet. You can record with the laptop or just use it as a controller with an outboard recorder or mixing device. "Mixing device" of course means you can run more than a pair of mics but I don't know how that works with the "RCS" controller software. Hopefully they were forward thinking enough for the software to read the ID number of the controller.
They do seem to be progressing with the product line, its not just a "make a few, see how it goes" type thing. You can get six different caps for the stereo set. A figure 8 has been released or isin the works. A mid-side controller has to be in their plans as well.
Right now, this is not only out of my budget range, it doesn't suit my needs. But it is something to keep an eye on for sure.
