IPV6 Anycast for streaming

Sun Aug 12 01:11:25 UTC 2012

Hello,
is a anycasted Prefix a good idea for Streaming?
here's what we're thinking about:
1. get a /48 from a LIR or a RIR and anounce it through Hurricanne
through several Tunnel server including Singapor, New york and
Amsterdam
2. run 3 diferent Icecast server  in each of the locations where
frankfurd would be the Master Server while the 2 others would be a
slave relay
3. Assign same Ipv6 address to each of the icecast server where we
would be using other prefix to do Inter server communication
so if someone is in North America would go through new york, if is in
south east asia would be throug SG, otherwise africa/Europ would go
through Frankfurd
is that a good idea for streaming performance ?
any other suggestion is welcome
Thank you
