   The 'myth' is that a Telebit spoofing a protocol strips the framing and 
checksum bytes, based on the theory that they're not necessary since the 
protocol used to transfer the data over the modem link is streaming and 
inherently error correcting.  If indeed this were done, UUCP-g would perform 
measurably better on a spoofed session than it already does (on the order of 
10%).

   The gain from spoofing a UUCP-g transfer at high speeds over high latency 
links (especially if the transport is half-duplex) is huge; however, if the 
'myth' were true, the throughput figures should be even higher.

         Coincidentally, most people who fight for "fairness" would be
         significantly better off under the system they call "fair"...
