Option #2 is easy enough to implement and, with some work, can avoid detection.
From what I've been able to gather, this is the only way they could be doing such massive data mining of Poker Stars (I haven't looked into other sites but I've heard security on anything besides Poker Stars/Full Tilt is quite horrendous).
Select a Shark Scope filter and define the order and visibility of Shark Scope statistics.
Then configure which Poker Stars nation should be used for Shark Scope searches.
Party Poker allows regular screen name changes and has optional anonymous tables for heads-up games.
