0install
Zero Install URI scheme
Register 0install: as an URI scheme. This would allow links in websites to trigger actions in Zero Install. Similar to Steam's steam: scheme.

This is at odds with FAQ -> Wouldn't it be cool if you could install software just by clicking in a web page? .
Of course, times have changed since that FAQ was probably written; I think it's about time we revisit that question from today's perspective 😉
Some thoughts from today's perspective:
The default stylesheet for 0install feeds provides two buttons "Run" and "Integrate" which provide Bootstrapper EXEs. These find the local Zero Install instance or download one if none is found, and then call 0install run or 0install integrate. So this somewhat replaces the need for a 0install URI schema.
These bootstrappers are generated on-demand, embedding a feed's URL. Therefore, they cannot be digitally signed, unlike the "normal" bootstrapper which has an AuthentiCode signature. Without such a signature modern Windows versions tend to show a lot of warnings before a user can run a downloaded executable, reducing the usefulness of this feature.
