----- you seem to presume (as did Mike Biel) that from one reel we get two 
reels. In a world where we could store each item according to its individual 
climatic requirements, this would be natural. However, why not keep it on one 
reel, only shuffled according to Eric's rule (1). This would only mean to 
stick end-to end that which has already been necessary work for the transfer 
process. 

The question then becomes a combination of "tails out?" and "acetate or 
polyester out?". I would propose SS-prone out, because that provides the 
largest radius of curvature of that part of the pack.

Discussions of file format "at great length" is never expenditure, it is 
investment, and you had better plan ahead.

----- well, the way I understand Eric is that it is already impossible to 
leave it the way it is, because it has been separeted to bits in the process. 
So, you could just as well be intelligent about re-assembly. And if you are 
using a system in which you need to keep your fingers crossed and hope for 
consistency and validity of the metadata--well, then your system is not good 
enough. If you can neither authenticate nor find information as to what you 
have done to the original, you could just as well discard it after having 
made the documented transfer. It all comes down to trusting the person who 
has performed the transfer.
