I've put together a SBT plugin called xsbt-coveralls-plugin that uses scct under the hood, but publishes the results to http://coveralls.io.
Disclaimer: I've only just built this plugin yesterday (10th March 2013) so don't expect it to be perfect yet, but do send bugs and feature requests to the github page
Still, it's good if you want to code coverage reports to be publicly visible. Check out an example of the results here
