Since I saw some more people answering, I am not anymore ashamed of promoting my little report on ethics.  It covers some cultural aspects as well.

Reference: Waern, Y. Ethics in Global Internet Research. Report from the Department of Communication Studies, Linköping University, 2001:3.

Part of it has been discussed in the AoIR meeting (through Malin Sveningsson).

If anybody wants the report, I can send it to you in pdf-format.

All the best wishes,

Yvonne
