During the 
[discussion](https://groups.google.com/d/msg/sage-devel/fE45025Wphs/mKdCAeNhAgAJ)
 
of the inclusion of OpenSSL, a few remarks were mafdeabout the security of 
our distribution infrastructure.


It has been noted that http is ridiculously easy to hijack 
<https://groups.google.com/d/msg/sage-devel/fE45025Wphs/3dfTByrIAQAJ>,  and 
some have remarked 
<https://groups.google.com/d/msg/sage-devel/fE45025Wphs/FheYtjBWAAAJ> that 
this potential threat also applied to the  http downloads from our mirrors.

*I think we should consider this issue, an plan to post (Real Soon Now) a 
call for discussion about this.* What is the relevant list ?

Others remarked 
<https://groups.google.com/d/msg/sage-devel/fE45025Wphs/podOAX89AAAJ> that 
a non-SSL-enabled pip, which impedes, for example, downloading from Pipy, 
sort-of enhanced security by suppressing a possible source of attack. No 
comments...

I have a few questions :
* Would it be difficult/onerous/cumbersome to ask our mirrors to switch to 
https-only service ?
* Would such a measure significantly lower the possibility of attacks of a 
Sage user/developer machine via "http hijacking" ?
* what is the likelihood of such an attack ?

Your inputs, please...
