A short summary of his writing: he didn't know about SAGE earlier, so he's just found out today. He will take a closer look at the project. He'd find it interesting to integrate mathGUIde into SAGE. About the licensing: mathGUIde is GPL (oh yes), he just emphasizes that the Qt noncommercial license for Windows is a bit restrictive, but in his view that shouldn't be a problem with Linux (but we want to use it with Windows, right?).
