Re: Unofficial Meeting of Scalable Small Group Multicast(SSGM) for IRTF

["Yuji Imai" <[e-mail]>]

Hello all

The room name is "Sapphire" in Hilton Anatole.
It is located 1st floor of the Tower. We will put a poster on the message board.

For tele-conf.
 We prepare our bridge and polycom for remote a participants.
 Mail <ug at xcast.jp_NOSPAM> & <yoneda.takahiro at
jp.panasonic.com_NOSPAM> for bridge information.
