I suggest to do the initial sync on a desktop computer to avoid the router the hard work.
When I say plug & play, the box will come preloaded with the blockchain (possibly as an option since some people might want to do this themselves)

Also, I already have a hardware manufacturer that would be able to build these out, and I'm most curious if people would be willing to invest in something like this? I might consider pre-orders, but would prefer to just have raw interest & just build out units.
If you quote the price in BTC people will buy it, people are able to spend "only" half a bitcoin on a bitcoin router.
Also share videos of the prototype before acepting preorders to gain trust.
