What I want for all these services (Little Snitch, ESET, etc) is an EasyList-like ... list. A community-aggregated and reviewed list of servers that don't merit my connection. I'd pay a monthly subscription fee for that.

I'd also like separate lists for

* "this wifi is public, be extra cautious"

* "this wifi is public, be nice and don't torrent, do backups, etc"

* "I'm on a metered connection (e.g. LTE), don't run torrents, backups, etc"

edit: for anyone looking for a monetizable idea: this post has 41, no 42, no 43 points in about an hour. Probably a good idea...
