A question about steganographic protocol design was asked on Server Fault. It appears to be off-topic on Server Fault. To me security.stackexchange.com seems like the most obvious site to migrate it to. Would it be on-topic here?
Kasperd - as it stands, the question would not be suitable on any SE site. The current structure has multiple questions, some unrelated and confusing information, and a title that muddies the water further.
If you could clarify it down to one question, as per our [ask] page, you could ask it here.
