Just today I started to look into RLPx to do some basic network discovery, so your guide is quite nice to have as a reference. But I had some difficulties getting started, because the RLPx spec was not simple to find (ethereum wiki -> devp2p -> RLPx) and is quite terse. I myself wasn't able to decode the packet structure.

Looking into ethereum related stuff I often get the feeling that one already needs to know half of ethereum quite decent to learn something new, which makes it hard to even get started.

Reading your guide (am not finished yet) gives me a better picture of the things I actually need to do, to start discovering some nodes, so I'm really thankful for that and hope for more beginner targeted ethereum content.
