I just got my copy of Instant memeory yesterday --I was shocked at how fast it was delivered!
The basic postulate of the book seems to state that memory can neither be trained nor improved upon, but merely 'released'. It states that, by nature, the unconscious mind is a perpetual recording device, a 24/7 tape recorder, naturally storing EVERYTHING photographically. It gives a method of releasing memories where one enters a state of relaxation (the "master relaxation technique") then gives comand to the unconscious to instantly and photographically release any desired memory.
I don't know that much about NLP but the comands seem to be based along those lines.
The book says to speak to the unconscious in the second person rather than the first, not to use negative comands etc. etc..
The fundamental concepts seem, to me at least, cogent. It appears some what simplistic but then again the simplist answers are usually the right ones.
Pete, does the Memory Optimizer course do anything along those lines; releasing the minds innate ability to remember?
If it does I'll be the first to buy it 'cause this instant memory book, though promising and logical in my mind, smacks of tedium and rather frightens me. 
I'll give it a try and post any succeses.
buy! (heh heh)
