when I run so2r on rtty I can decode 4 streams at once, 2 vfo's on both
radios... I have been known to run 5 radios at once on rtty, so that would
be 10 streams if each were decoding both vfo's... where does that fit, and
how many special rules do we make to allow for it.

and at what bandwidth do you define 'assisted' for a bandscope?  Many radios
have had wide band scopes for years... some cw operators can use 3khz or
wider filters and decode multiple signals, I can't, should they be assisted
because they have better brains where I need hardware assistance??
