It would be nice to support uploading coverage to coveralls and other services.

I think the problem will be how do you collect coverage information, at this time kcov may be the choice (not sure if we have other choice).

There are several updates to this blog post. Do you think this is easily doable now ?

tarpaulin could be used for this, but it's really slow (even on my machine). It seems to rebuild the project twice with nightly, thus breaking any possible cache usage.

If working, tarpaulin seems more ergonomic. kcov can, in addition, generates an html report that can be inspected locally.
