That's more than walking on the blending edge, just my opinion.

With my personal systems I do really scrapy things ... "waling far away from 
the blending egde" ... but not with production eviroments.

No, it's a matter of been well done, moreover taking into account that are 
python scripts, not C or C++ code that depends on lot of libs.

That's not true, lattest Debian Stable release 5.0r0 that is from 6/29/2009, 
so not "years ago" as you suggested.

And that's an admin task ... so what's the problem with this?

Also not true, at least with Debian.

Mediaproxy it's not a blending edge software (from my point of view), it's 
true that NOTHING could be called "stable" for sure, but on Debian unstable, 
packages are not warranted to run, ever to install without crashing all the 
system (on a normal way, that does not occurs, but you don't have any warrant 
of so)

But this is only a matter of POV's.
