We could set up an encrypted `vat' audio session between the locations. Cygnus has T1 connectivity to the Internet. Someone would need to provide a good self-powered speaker to plug into the Sun audio port (a standard mini phono plug). We have a microphone that will possibly work, though we should run some tests before the meeting. Cygnus does not have multicast support, so we can't feed the `mbone' (multicast backbone) with it, but we can attempt one or several point-to-point links. `vat' runs on Suns and is available from ftp.ee.lbl.gov or ftp.cygnus.com:/pub/vat.1.56.tar.Z. It's `Van's Audio Tool', unfortunately available only in binary. Its encryption option requires that the participants agree on a key in advance, and type it into each workstation at the time of the conference. John Gilmore
