Thank you for notice. It means I can stop wasting my time here and talk to people who actually listen.

No comments, just hints for potential investors:

Well that is good news; when he settles on a design he'll get the best price for the parts before 3D printing the PCB.

Maybe he can 3D print the ASICs too!  >:D

The only thing done on the CPU is display the data and interface same as every Oscilloscope. Why did I bother writing it and including pictures. If you can´t understand a basic sketch I really can´t help you

Pro tip 1: you don't even understand what those people are talking to you about
Pro tip 2: and it is not because they are babbling nonsense :P

Pro tip 3: watch some reviews of scopes or read the T&M subforum to first understand what people expect from the final product
Pro tip 4: even if you think opinions of reviewers and other Internet oracles are wrong, their opinions still affect your marketability

I'm still wondering if it would make sense to start a Kickstarter for an open source oscilloscope software framework (without going into a detailed discussion on what kind of acquisition hardware should or shouldn't be used).

"Oscilloscope software framework" is way too vague goal. Definition of target hardware list/options will greatly help to get support from backers. BTW Sigrok is halfway there. Would be shame to not use at least partial code of it. For instance Sigrok community implemented quite enough protocol decoders...
[edit] For me open questions are: 1) Linux or lightweight RTOS 2) broad connectivity (Ethernet, USB, HDMI, parallel LCD) or not. Clear benefit of Linux: hardware & I/O support.

nctnico:
Linux platform for sure. Ethernet, USB and parallel / LVDS TFT interface for sure. Beyond that it starts to become hardware specific.
There are basically two ways to go: use a Xilinx Zync to have an all-in-one solution or use an FPGA + SoC. What I like about a SoC solution is -that if it has a GPU- it will be much easier to extend the functionality using OpenCL rather then needing FPGA development work for decoders & math. I have not looked deeply into OpenCL yet but it at least has a C-ish syntax. In theory you could implement a form of OpenCL scripting for signal post-processing at very high speeds.
