Apologies for that last email, Thunderbird wasn't too nice with ASCII.

Here is a rough draft of our usual topology. Imagine a few more
"Players" section scattered around the 2x10G rings.
We are already planning for IPV6 but that really depends on our
upstream ability to actually provide the feature. Very good point
about BCP38, that is not something we had considered. We usually
segment the network for each row of tables which usually ends up being
48 players in the same vlan.
Thanks!

We were looking at either the Nexus 7004 chassis or the ASR
9004/9006 chassis as the core "switch". We would then use 48xGigE
and 1x24 SFP+ line cards. Our actual port requirements and somewhat
flexible but we do need at least 4x10G Fiber ports. And at least 48
GigE ports for players or access switches.
I don't really understand your topology. 2001-2004 I was involved in
providing network connectivity to around 2500-4500 users at
Dreamhack, back then the largest LAN in the world as far as we knew.
Back then we made do with 2x100FE for 20 computers and the core
connectivity was 2xGE. I'd say your design seems to fairly similar,
but with 2x10GE instead, but I'm just guessing from what you wrote.
ASR9k has been used before and will do just fine. Dreamhack has grown
a bit since I was involved:

I'm also open to any suggestion within Cisco portfolio. Our needs
are pretty standard and nothing extraordinary but we would like to
use this opportunity in order to try new equipment and technologies
that are usually only seem within ISP and large networks.
Don't forget to provide dual stack (IPv4 and IPv6) connectivity.
Limit your broadcast domains (I'd say 20-50 users per broadcast
domain), and make sure you do antispoofing (BCP38) for everybody.
