I think I like this idea.

Looking at the current language it says "other participants (minimum of 
two total)", to be honest I find this language a little ambiguous, I 
could interpret that as simply two participants, two participants plus 
the exchange, or two participants plus the participant making the request.

I think a requirement of three registered ASNs peering, one of which 
could be a route server for the exchange, not including any private use 
ASNs, its an Internet Exchange not a private exchange.  In my opinion 
two participant ASNs plus a route server ASN or there participant ASNs 
are sufficiently differentiable from private peering.  However, just 
simply two participant ASNs is insufficiently differentiable from 
private peering.

Fees aren't a policy issue, we could recommend to the board that IPv6 
micro-allocations to IXPs that already have resources be free.  But it 
should not be written into a policy statement.
