Not Rev, just your time.

At a quarter-millisecond per access, even the slowest method shown here 
may not be bad.  And if this needs to work on multiple files there are 
ways to speed it up exponentially.

If you took the time to write your own external, unless it does 
something highly specific on a whole directory at a time, I suspect the 
net runtime would be roughly on par with what you can get in native 
Transcript in a fraction of the effort.

I've been down this road before, most recently with an installer I'm 
working on for some of my clients.  I've sliced and diced this problem 
from a few different angles, and the recommendation I offered to you was 
the result of that effort.  Sorry if my attempt to help you find an 
immediate solution struck you as "bizarre".

Best of luck -
