Firstly thanks to everyone for the debate. My primary intention was to 
advocate incorporation into pdfTex -that was irrelevant within an hour or so 
of my message. I have certainly learnt much from the subsequent comments 

Many of the points have no solution, they are (to quote myself) "balances". 
Is it more over-bearing to presume that people will behave rationally or to 
try and stop them behaving irrationally or to ...... ?

	Agreed, but I (and others will differ) was not purusing absolute 
verifiability. I was happy with a "threshold" that it would be difficult for 
someone to claim to have crossed in good faith.
	After all, 'real' company accounts to members are not 
individually signed, merely printed. One might accidently mis-report what

computer-illiterate . . . or honest?
	In Geneva newspapers used to be sold from open trays/boxes
 in the street, without vendor, and a box to put the money in. It worked 
(though one doubts 100%) (and the money box was 'closed' ;-)> !).

P.S.   Interesting as all this is --and I don't want to try and grab the last
