I don't think a 'series percentage' of relays are in EC2.  I would
politely ask you to research that and prove me wrong if you feel
strongly about it.  There might be a serious percentage of bridges,
but even that is questionable.  (Related: Runa is giving a talk at
Defcon on the Diversity of the Tor Network, so hopefully that will be
a canonical answer to these sorts of questions once her slides go up
in a couple weeks.)

Regarding their ability to monitor EC2 - well it depends on what
datacenter.  The bulk of EC2 is in the Virginia one - and yea the NSA
probably has a line on that one or it's upstream ;)  But what about
the one in Singapore?  /shrug
