// The basic idea is as follows:

// We may know a NodeID (with a mask) and want to connect
|
||||
// We begin a search by initializing a list of all nodes in our DHT, sorted by closest to the destination
|
||||
// We then iteratively ping nodes from the search, marking each pinged node as visited
|
||||
// We add any unvisited nodes from ping responses to the search, truncating to some maximum search size
|
||||
// This stops when we either run out of nodes to ping (we hit a dead end where we can't make progress without going back), or we reach the destination
|
||||
// A new search packet is sent immediately after receiving a response
|
||||
// A new search packet is sent periodically, once per second, in case a packet was dropped (this slowly causes the search to become parallel if the search doesn't timeout but also doesn't finish within 1 second for whatever reason)

// Some kind of max search steps, in case the node is offline, so we don't crawl through too much of the network looking for a destination that isn't there?

// Each time a node responds, we sort the results and filter to only include useful nodes

// This happens in parallel for each node that replies

// Meanwhile, we keep a list of the (up to) 16 closest nodes to the destination that we've visited
