I will try that and see if it is able to continue through the 
problematic period.

It is usually the same machines that have problems, and they are behind 
the same network link. The script runs from cron, so I guess it is more 
or less on the same time every day.

I have no problems with that. Just remember some attribution. :) From 
what I know the build script works without problems on Ubuntu 6.06, 8.04 
and Debian stable. I haven't tested it on any other platform.

I assume it should work pretty well on any RPM platform too if you just 
replace the apt-get call with some yum call. If you want to, you can 
also include it in a contrib folder or something in the main package. 
You can use the same license as duplicity.

I guess that if you use "lsb_release" or something similar, you could 
even make it build on different distributions, as long as you know what 
packages are already packaged in the main repositories of the 
distribution. With some work you can even make an "automatic" build 
system that downloads the build script with curl/wget and runs it 
through bash to install. Wildly unsafe of course, but very convenient.
