Yes, the hardware can support 24/192. The DAC can do it and the oscillators are of sufficient frequency to support it from the processor. The one issue is optical out. The TOSLINK modules being sold today do not have a high enough bandwidth to reliably handle 192. (Toshiba used to make a high speed one, but they don't make it any more). The Coax S/PDIF out should have no problem with 192.
There are several "levels" of software support that have to exist in order to do it. First is the ALSA driver. I don't know if that supports 192. I've used it at 96 but I haven't tried it at 192. It should be easy to try. Just try and play a 24/192 wave file using aplay and the HW interface. If the driver supports 192 it will play, otherwise it won't. If it does not support 192 then the driver will have to be modified. Given they have a working driver for 96 adding 176 and 192 should not be too difficult. Then there is the audio code inside squeezeplay. It has to know that 192 exists and can be sent to the ALSA driver. I haven't checked the code for that. Then there is slimproto or whatever they are calling it now. The actual streaming protocol has to know about 192, and sqeezeplay has to recognize that and do the right thing with it. Last is SBS. It has to know about 192 and know that something is 192 and what to do with it. Since it is currently being downsampled it seems like SBS knows about it. So it most likely needs to be updated so it knows the Touch could play 192 so it won't resample. So the two biggies seem to be: does slimproto handle 192, and does the Touch ALSA driver support 192. So yes it IS just software, but there might be several pieces of software that need to be updated to make it work.
