The OCSP is used to ensure that in case of security breach the certificate can be revoked dynamically. If you don't care about the "dynamic" part then you can skip the whole OCSP process all together. Now you are in the same state as you will be with embedding your server cert in the app without the need to "hack" the system.<p>BTW, nothing prevents you from using your own certs. Just make yourself a CA, add root cert to the app, and implement OCSP on your server (if you care about OCSP). Again, no need to hack it and invent new security protocol. Everything you need is already there.
