[Unison-hackers] Asymmetric DSL and large files

[Benjamin Pierce]

Hi Stefan,

I'm afraid I didn't really understand your question the first time,  
and I don't really understand it now.  Unison has to propagate the  
changes in your file *from* the machine that has the new version *to*  
the machine that doesn't, no?  (If all you want is to make the two  
versions the same, then you can tell Unison manually to overwrite the  
new version with the old one, and then you'll be utilizing the network  
in the fast direction.  But usually that's not what's wanted.)

Best,

     - Benjamin
