Getting back to outstanding pull requests; What's the intended purpose of this? Practically speaking goconvey is very tied to the source under test. It doesn't make a lot of sense to me to use a separate binary.

Not sure if this is the intent, but I should like to be able to generate a HTML report using my CI tool and then look at the result in a browser at a later date (should I choose to do so). Having the pretty Web UI is great for fast feedback as I write code, but if tests fail in the CI tool, it would be great to see the pretty Web UI there too.

Hm... I think that may be a different request then; Potentially go test could grow a flag to emit a static HTML report.

Note that if you're looking for coverage from your CI tool, the coverage reports are using the built-in go test coverage reporting and html generation.
