Decision on how to protect PPT presentation against modification

[Klaus77]

I currently use PPT97 and I am trying to protect presentations against
modification. I don't mind the recipient to make print copies.

The PPS-route is a joke, but I understand that PPT2003 has a real password
protection.

How strong is the encryption? Is it worth getting PPT2003 for this feature
or is it quite easy to work around?
I know there are some password cracking programs that can open almost
anything.

The question really is: does one have to be a really determined expert to
crack it or can the average user do it too?

How safe are the alternatives "Thinstall" or "QPresenter"?

Klaus77,
As you already indicated absolute protection is an illusion.
