I have multiple computers, both of which I use for some part of DND. I use my desktop to plan adventures and research ideas, and then my laptop to run a session because we often do not game at my house.

If I were to buy the digital PHB would it be locked onto one of my computers forcing me to buy 2 copies? Or would there be some other form of security preventing people from just handing out PDFS of the books?

If anyone knows that would be great, I don't really relish the idea of buying the same book once physically, and twice digitally.

I haven't seen any word on this of yet.

I'm betting the do SOME form of DRM, but what that form will be is anyone's guess for now.

I'm hoping that we'll hear more at DDXP. . . if not sooner.

yeah, they have not even hinted at the level of DRM.. they should have a basic solution by now.. just wish they would announce anything.

On a similar note, I keep all my D&D info on an external hard drive. What if I need to plug it into a different computer? What if it's just time for me to go and buy a new computer? I really don't even want to buy an e-book if I already bought the print version, but I really don't want to have to buy that e-book again and again and again.

... I did just buy a nice WD passport, 160 gig. I guess it might have some room for DND info. Thats something I sort of can't believe I didn't think of. Hopefully it osn't register the products to my IP, and will only register it to a specific harddrive.

Linked to th computer how? is it locked to a single harddrive, single IP address, some other method?

If it is a single harddrive that is as simple as taking out and moving the harddrive to a diffrent computer.

in Acrobat reader, you have to enable certian security settings, and follow a wizard. It sets up a digital id via some net authentication for the machine name and user name, and I am sure a bunch of registry keys.

then your downloaded document is registered to that ID. the document itself is still a PDF, but with the DRM enabled, it then checks for the digital signature setup in acrobat before it allows it to be opened.

you can copy the file all over the place. but nothing else can open it except the id it is registered to.

An the ID would be registered to a specific computer, not a harddrive? Thats what is confusing me. -Not a huge knower of how DRM works, I don't buy music with it-

I am trying to figure out how it signs to a spcific computer, the computer is an asembly of parts. Thats like saying -to me- you store memories in your body. They are stored in the brain, but the brain is in the body.

Basically, there's a variety of methods one can use to "fingerprint" or otherwise ID a computer.

Windows gets its settings for almost all of its programs (and for Windows itself) from the Registry. This means most registries are fairly unique (due to what you may have installed, what your Windows registration key is, when you installed Windows, etc).

You also have hardware that's probably fairly unique.

Software programs *can* take a "snapshot" of your unique hardware, software, and registry configuration and create a code from that. This code is then placed "inside" the PDF.

When you open the PDF it takes a new snapshot, and if it isn't the same (or because you can make small changes like adding/removing memory - REASONABLY the same) the PDF will refuse to open.

It's one option at least.
