Their game is just to try to make the ISPs liable; they don’t actually want it enforced. In fact, failure to enforce is the feature. They paint the ISP as complicit in the piracy then sue the ISP for hundreds of millions in damages hoping for a no-fault settlement. That’s a much better revenue stream than suing someone for 10k who can’t pay it.
We called them “luggables”. They’re expensive, but having a server in a box with a monitor was worth it when you could lug it to a customer site and give a live demo of your server stuff. We were doing telephony stuff and you could put a $5000 dialogic pcie card in it and demonstrate call handling live. We can do that with software on a standard issue laptop these days, but the luggable helped seal the deal back in 2005.
