My book(s) will be useful but I think less compelling than yours, 
so I'm not too keen on an account hurdle. but I am wondering how 
I might use the PayPal reference number to add a touch of 
security. One publisher puts buyers' names in the pdf, but that 
is through Open source, which I have been eyeing idly for years 
without considering the water warm enough to jump in ;-).

Try to make time to follow through on the advice from you, Tim 
and David - for which thanks all.
