I would be interested in being involved in a project to create:
A standard protocol to feed sample data (analog signal samples and digital data samples) from something like the DSO Nano 2 or DSO Nano Quad or beyond to a Linux or Windows Oscilloscope program or even to the Pump … via USB2.0 or USB3.0 or possibly Ethernet as well, although USB3.0 should be good enough for most applications.
A Windows/Linux Oscilloscope or even mixed signal scope program that can take such data in and display in various ways.
I have been involved with Open Source projects before, like Ethereal/Wireshark, Samba, SCST etc.
I think that developing new USB-only oscilloscope without screen/etc but with optocouplers will be better approach.
Something similar to USBee DX
This device was already revesengineered (see for example kazus.ru/forums/showthread.php?t=14159 (sorry - Russan only))
If that is what you want to do then I encourage you to do so.
However, I personally think that a different approach would be interesting … Most importantly, a standard format for communicating these data streams would be very useful … and it will not be XML for live streams because of the order-of-magnitude bloat that XML causes.
However, off-line processing of XML would be interesting in existing applications like XOScope …
