Discuss: protocol weights in scoring algorithm

[raulk]

Our connection scoring algorithm performs a basic sum of the values of all tags in a linear fashion. However:

• some connections may be more important/valuable than others.
• values do not represent the same thing across algorithms; in some cases they may be latency, packet loss, behaviour-based, etc.
• blending distinct factors into a single value that can be fed into the pruning heuristic is challenging, and warrants further research/exploration.

I don't have a concrete proposal, but I didn't want this train of thought to fall off from the radar.
