Re: [Duplicity-talk] 0.4.3.RC6 Ready for Test

[Kenneth Loafman]

Possibly, but that's the way its done for SCP and others.  Not really 
suggesting that we change it to go that route, but looking at the 
alternatives.

Another route to go would be to use the background mode in ncftp. 
Duplicity would just control the queuing and cleanup.  Or we could just 
use expect to control a known good FTP client.  Or...

Just thinking out loud, trying to get a brainstorming session going.
