Problem is we're running out of bits. Let's see what drH thinks. We certainly are running out of options bits and will need to do something to address that at some point it hasn't been decided precisely *what* yet. However if the option is related to certificates it can use the cert_flags field in the CERT structure. If it is related to mode then it can use the mode field. Both of those have plenty to spare.
