So, since you sound like a somewhat higher end user:

1) What platforms do you care about? Do you mainly need service from one fixed location, or from home/office network plus mobile?

2) How close does it need to get to the endpoints? We have 4 exit nodes right now; we'd probably need ~50+ to be very close to most services. There's still a portion which is "in the clear" (although, use https...), but it becomes very impractical for NSA or especially others to passively tap all those locations (since they wouldn't be IXes necessarily, and intra-colo links don't get routed through buildings like ATT 611 Folsom St.
