There is another great tutorial that Zhao Lu (aka – @zlu) has done, showing how to use Tropo with Google Wave. Zhao takes JRuby, the Rave gem (created by Jason Rush, aka @diminish7) and creating a Google Wave Robot that allows you to create a callable conference in a Wave.

The complete tutorial and code example is available on Github @ http://github.com/zlu/tropo-wave-tutorial. Thanks again to Zhao!
