5 years ago Yes, the NeTV2 will be usable for this - but it will require a bit of work.
The FPGA is the same as on the already supported PCIeScreamer and AC701 boards - Artix7.
However the NeTV2 is a bit limited in the ways the "attacker" computer may communicate with it. The HDMI isn't really suitable for this (even though I guess it should be possible in theory). The micro-USB looks like it's UART only - i.e. slow. Remaining is the 100MBit Ethernet. This would give us around 10MB/s over the network. Since there is some overhead I guess we would realistically be looking at dump speeds around 8MB/s unless a compression is added as well.
So yes, it would be possible, very useful, but the speeds wouldn't be great. There will be some work involved. I may look into it myself, but I have so much other things to do chances are that it will take a long time. My things are open source so if you'd be interested to help out I would be happy to accept a PR.

Conceptually, Is there any reason that this couldn't be ported to work with the NeTV2? https://www.crowdsupply.com/alphamax/netv2
