Three problems with that system - one possibly easy to fix, the second
harder but more of an inconvenience than a problem, and the third a bit
of a stumper but possibly acceptable while we're waiting for direct
neural interfaces to become available:

1. Playback mechanism.  Audio and visual playback have been done.
Acceleration (including different accelerations for different parts of
the body) can kind of be played back via haptics, but that's currently
at a fairly primitive level compared to audio/video.  (And that's
assuming differences between different people will not present a
problem.  Hieght/build differences seem easy to get around, but e.g.
erotic content - which, if you check the history of other recording
media, is likely to finance a great deal of this system - might be
difficult to translate from male recorder to female playback or vice
versa.)  Heart rate is most often sensed internally, where most people
would not want playback hardware inserted (and where it would be costly
to do for those who are okay with it).

2. Playback time.  Playing these memories back, so they can be
transmitted into someone else's memories, takes as much time as the
original did to experience.  Perhaps the memories can be edited into
just the highlights to partially alleviate this, but certain
experiences really do require long sessions to properly experience.
(A rested person will have a hard time relating to an out-of-breath
marathon runner crossing the finish line, at least without consciously
applying filters to the experience.)

3. Playback intent.  We are in all kinds of mental states throughout
the day, but someone playing a memory back is probably intent on
playing that memory back.  Would this not create a fundamentally
different qualia of experience than what the original recorder
