Simply Silverlight is a plugin for deploying Silverlight content in WordPress websites.
Not yet. Currently it's only available in English. However, the plugin is ready to be translated. It includes the Portable Object Template (.POT) file needed to make translations. If you would like to translate the plugin into another language, please do so. You may send the translation files to email@example.com and I'll include them in the next release. Thank you for your assistance.
