I found my answer by reading their requirements more carefully
"CE4 plugins are not standalone software, and require Lightroom to run. Content should be published to the Web via FTP, requiring a domain name and standard web hosting. Hosted website services such as those provided by LiveBooks, Squarespace, etc. do not qualify as standard web hosting and are incompatible with output from TTG plugins. For quality, affordable, TTG certified hosting, we fervently recommend Bluehost."
