This is really a continuation of
this thread. But due to my poorly worded question that thread went awry.
It suggested take ADE with you, or don't get the book. But,
Assuming you need to use ADE and you have access to a computer with ADE installed and access to the internet.
Is there any problem with de-authorizing (<alt><shift>d) the computer re-authorizing the computer with your adobe ID, downloading the book and transferring it to your reader and then de-authorizing the computer again?
Or, even easier, is there a portable version of ADE, that works?
