I don't know the detail, unfortunately, but if disabling e-tags is in 
essence what I was asking you for, that's the option I (personally) would 
prefer.

There's a difference between backing up a TW when it is first opened from 
disk and backing up on a save-by-save basis.  I'm assuming we're talking 
about the former, not the latter.  The former is what I assume you mean by 
"version history".

I already have that in place and don't see any need to change it, though I 
maybe would if I felt the need -- can't imagine what that need might be 
though.

As regards the time window... any code that takes a "best guess" at the 
appropriate period of time is likely to suffer from distrust.  Also, I have 
some wikis that are open for weeks and many others that are transient 
throughout a single day.  Some are modified a lot, others rarely.  I just 
don't know what time period I'd pick.  And then I'd always wonder if my 
next save was going to suffer a 412 because I'd chosen a poor "best guess" 
period.  Hence, distrust.

Really, honestly, I'd prefer no time checking at all.  Then, as I said 
above, TS would become usable (and, trustworthy).
