This is actually something I have been thinking about doing, but implementation platform for me is of course N9. (no reason though why it wouldn't be easily portable to N900)

Call scenario is something like this:

start call normally as a a/b subscriber voice call
at any point both callers agree to switch to encrypted mode and start the application
both ends authenticate PKI
when the exchange is complete the voice transfer is transparently directed through the encryption layer
