After a little delay, here is the updated Tournament Approval document:http://thenaf.net/downloads/NAF_Tournam ... c_2011.doc
Point 4 of Pre-tournament requirements
refers specifically to nation vs. nation (or state vs. state etc.) events re NAF ranking.
If Eurobowl is to be NAF-ranked, then all teams would have to fulfil this requirement.
About 9 months to go, so plenty of time
