Daft idea for commercial software ???

[Richmond Mathewson]

  I have been thinking about all the cafuffle about registration numbers 
and so
forth; and wonder, given the fact that some level of pirating will go on 
if a piece
of software is worth anything, if it is really worth all the mucking around.

So:

I should like to float this idea and welcome all reactions and criticisms:

I release a crippled demo which contains a page that lists my Paypal place
and informs would-be buyers that within 48 hours of my receiving via
Paypal I will either e-mail them as an attachment or direct them to an 
ftp folder
where a full version of the program is with a banner of some sort plastered
across the front page / opening screen saying something like:

"This version of ZZZZZ is the property of QQQQ and as such may only be 
used by
him/her/it."

No doubt some folks will share their personalised versions with their 
friends,
relations and so on; but that will probably happen anyway unless I go down
the painful route of tying programs to mac addresses.
