I have been playing a fair bit of GameNet recently and I have to say that I've fallen in love with it. It's a very versatile ID, which means that the runner never quite knows what to expect. I have been playing a "fast glacier", with as many taxing ice as possible to cripple the runner while I fill up on credits. Endless EULA is particularly fun, giving you six credits if they decide to pay to break, although the reintroduction of Parasite with Salvaged Memories is a bit of a bummer for it. I run Remastered Edition, Project Beale and Bellona as agendas, which synergize very well with the ID. Tollbooth is a must as well. Even Pop-up Window gives you two creds for zero rez when they let it fire!
Some reviewers say that this ID isn't great because the runner controls the trigger and you won't gain cash if they don't run. That may be true, but it might be because of your ID if they don't run. And if they don't run, scoring a Remastered or a Bellona quickly will remind them they should.
