Yes, until the html/css/js part. There is a tool that puts all your files into an js object and provides your files like a virtual file system. Obviously doesn't go well with bigger files. I wish there was a way to use PE's / ELF's existing ways to embed files, especially for memory usage reasons.
That sounds like a very good p/l. But I'm still not convinced as it is still common for cloud providers to 'randomly' close accounts without warning and the possibility to appeal.
