No.

ANS' commercial connection customers are able, by virtue of their recent
joining of the CIX, to route packets to and from CIX members.  

HOWEVER, the ANS GATEWAY customers (ie: mid-level and regional network
providers) DO NOT gain this connectivity for their customers unless they
also join the CIX.  In fact, ANS doesn't have to be a member for the Gateway
customers to join -- I understand a couple of them are in fact members
already.

Thus, their recent announcement gives their <attachment> customers (ie: end
user organizations) CIX connectivity -- but does NOT give their resale 
customer customers (can you parse that :-) CIX connectivity.  The gateway
customer networks <themselves> get CIX connectivity out of this.  

Where it gets blurry is for those who sell, say, SLIP access.  Is a SLIP
customer on the ANS Gateway customer's network number supposed to get
routed or not?  This is a loophole in that there is really little you 
can do other than not route the gateway's network numbers to prevent
this from happening -- but the gateway organization <itself> <IS> entitled
to CIX connectivity as a result of ANS joining.  If you want to be a stickler 
for what the CIX is <supposed> to be from their agreements and such, then 
those customers of the gateway organization should not have CIX connectivity.

See above.
