ZeroTier is cool. With it on, I can just grab a file / test something on my laptop without needing to expose it publicly and either setup dyndns or grab my laptop's assigned IP address. I can just keep one bookmark for each service.
As a bonus, it'll route directly, instead of through an Open on server, etc.
I just wish they had an alternative to curl | bash. Something like Docker's install instructions, where you don't have to look through the install script to figure out what's going on inside sudo.
The curl | bash just figures out your distro, adds the appropriate setup to your package manager, and installs a package. You can do it all by hand if you want.
ZeroTier's pretty damn cool, IMO: https://github.com/zerotier/ZeroTierOne
