[CQ-Contest] Blind Mode for N1MM Bandmap

I think Dave, Tor et al have raised an interesting issue. There are
really 3 cases here:
1. local CW Skimmer in blind mode - signals are not decoded, and so
Skimmer doesn't know which signals are runners, and which are S&P. In
this case, it is simply a very good band-scope, well-integrated with
2. A local Skimmer in decoding mode, telnetting spots to software (such
as N1MM Logger) that is set up in "blind mode" to discard the callsign
and substitute a marker on a bandmap. The Skimmer's machine
intelligence would be deciding which were runners, and discarding the
rest. This would potentially be a big advantage for S&P rate, if you
knew in advance which signals were runners, and could jump from one to
the next with a keystroke or two. Such operation should be classed as
3. A remote Skimmer (or the RBN), with software as above. I'm not sure
how much advantage the "remoteness" would confer, beyond engineering
ease, but I think it would be still be illegal for non-Assisted
stations, for the reason in 2 above. If you are going to operate
Assisted, why not use Skimmer or the RBN with full capabilities?

Blips on a bandscope are fundamentally different from frequencies taken from telnet: For example, with what you suggest, you could take DX spots from a skimmer in Europe during a 160m contest. That way you would know where the EU DX stations are on the band even before the band opened to you in North America. In such a contest that would be a huge advantage even if it didn't include callsign information.
