Thanks! Good to know we have an official stance on the matter. This makes corporate troubleshooter a billion times better!

 I do not have access to my rulebook at the moment, but doesn't the run example from it have the Jinteki player rezzing Akitaro just before rezzing a piece of ICE?

 The Timing Structure of a Run chart has the Rez symbal as an option just as a Runner approaches ICE. At the top of the chart it says (purple rez symbol = Cards can be rezzed). It doesn't say Ice can be rezzed, it says cards. It also says paid abilities can be triggered at the same place. So I would say, rez away with whatever cards you want.

What's causing the debate is the way the Timing Structure is setup. It gives rez as an option when approaching an unrezzed piece of ice, but not a rezzed piece of ice. Lukas has already just about said this is a mistake, but we need to wait until he has had a chance to look into more. Maybe he'll let us know for sure in the FAQ.

2. The Runner APPROACHES the outermost piece of ice not already approached on the attacked server. …Either the Runner JACKS OUT: go to [5] (cannot jack out if this is the first ice approached this run)

…Or the Runner continues the run: if the approached ice is REZZED, go to [3]; if the approached ice is UNREZZED, go to [2.1].

2.1 (only time the approached ice can be rezzed) **symbols for rez and paid abilities appears here**
…Either the Corporation REZZES the approached ice: go to [3]
…Or the Corporation does not rez the approached ice and the runner PASSES it: go to [2] if there is another piece of ice protecting the server, go to [4] if there is not another piece of ice protecting the server.

3. The runner ENCOUNTERS a piece of ice. **symbol for paid abilities appears, but not the rez symbol**

3.1. The Runner can break SUBROUTINES on the encountered ice.

3.2. Resolve all subroutines not broken on the encountered ice.
…Either the run ends: go to [5] …Or the run continues: if there is another piece of ice installed protecting the server, go to [2]; if
there is not another piece of ice protecting the server, go to [4].
