It seems to me that if the group velocity can be sensed at 3*c then that
constitutes data transmitted FTL.

Live data can thus be sent FTL using parallel data cables (or fibers) for a
single bit (a bundle), and parallel bundles of cables for a binary word,
provided it is known *with good confidence* an interval for the arrival of
some indication of the value of each of the parallel data bits in a word.

Multiple cables can be used to transmit each bit, including multiple cables
to transmit (initiate) the timing (strobe) pulse which starts the sensing
interval for a binary word.  In this manner multi-bit words can be sent FTL
asynchronously.  The first indication of a signal on any cable for a given
bit then sets that bit.  This would not be 100 percent reliable, but
neither is any other form of transmission.  An indication of both a 1 and a
0 value for a given bit would trigger error processing.  If 32 cables were
used to transmit a pulse indicating a 1 bit in a given position of a binary
word, and 32 cables used to indicate a 0 bit in that word position, then it
is known with great reliability much faster than the speed of light if a
given bit is 0, 1, or in error.   Transmitting an 8 bit byte (with parity)
in parallel would take 9*64 + 32 = 608 cables.  It may be worthwhile to
dedicate 64 cables to the timing pulse bundle, which is always a 1 bit, for
reliablity in identifying an earliest possible start for the strobe window.
The 640 cables is extravagant, but so what.  It's just a proof of
principle.

How sweet it is!  And flouride protected too.
