Plugin Request: TinyMCE for Text Widget

Hi,
I have a plugin request for WPMU DEV! Users constantly fumble over the code in the text widget. There is a great old plugin - WYSIWYG Text Widget that puts TinyMCE into the text widget for editing content. I would love someone to update that plugin or create a new one. AND add the ability to recognize shotcodes. Could it be safe? I read that there maybe security issues with this type of plugin.
Thanks!
