Or, to 'reverse-engineer' C5's post:
If the doc's not too huge, you could print, scan, and then distribute all of the document as a .pdf or word doc or even a series of .gif's. Doesn't get over C5's reservations - but, as you've pointed out, the recipients could copy-type the thing in any case. Even if you watermarked each page before scanning, that could - in theory - be reproduced by the recipient.
Depends on how much trouble you/they are prepared to take...
