Yes, explicitly working around the quota system would be considered abuse. Simply shipping an application that makes requests against both V1.x and V2.0 isn't, though I wouldn't encourage it (outside of the narrow case of moving an existing V1.x app onto V2.0 over multiple releases). Also, remember that V1.x's days are numbered. Once we're confident in 2....

The ip, and user/app-pair quotas are separate in V1.x and V2.0. The "30 simultaneous requests" throttle is not, as it's a DOS counter measure.
