rspec-webservice?rspec-matchers-webservice?rspec_webservice?... or something else? The naming guidelines don't quite seem to address this case:
rspec-webservice seems correct because I am "adding functionality to another gem". But this will correspond to the gem residing in RSpec::Webservice, and I'm not the maintainer of RSpec, and so a naming conflict can arise.
rspec-matchers-webservice is a possibility because that seems to be how the RSpec library itself is organized.
rspec_webservice is a safe option, because it will simply be in its own root namespace (RSpecWebservice), and conflicts will be ruled out because the rubygems system will ensure that this name cannot be used for another gem.
rspec-dogweather because it doesn't greedily use a generic term?
