Is there any development underway to use calibre to make the e-book MORE secure? For example, in the Windows environment, or an SELinux environment, the OS could be locked down while calibre was running. Such a lockdown would prevent screenshots and the starting of any debuggers such as IDA Pro. If done in conjunction with some new extension to a popular e-book format, such as epub, the extended epub format would be a good protector of the books IP.
