hop:// (in Firestorm at least) continues to work pretty well when
shared in Chat/IMs and/or used in the top address bar... but not in
the map too where <a href="http://gridname:port">http://gridname:port[/region] is required.
Just to pop some links and posts from 2013-2017 about this topic here
in a handy form...
Cinder Roxley is developing a multi-grid teleport addressing scheme
that works in a similar fashion to hop:// in that it can be used to
launch or communicate with a running viewer and teleport to a
specific grid, region and location, as well as run certain app
features. It is being implemented initially in the
<https://alchemyviewer.org/pages/downloads.html>Alchemy Viewer. More
details of the protocol are available at
