[HECnet] Connecting to HECnet from DEC Legacy 19-20 Oct

I am hoping to connect to HECnet from the DEC Legacy event in October, hopefully connecting a few interesting systems to HECnet and allowing attendees to explore HECnet. I would be using a USB 3G device to do this, so I wouldn t know my IP until the day itself. Is there anyone with a bridge on HECnet who would be available during UK daytime on those days to configure their bridge to peer with me? There may be more than one change of IP address over the course of the weekend though. Are there any other options? Thanks Rob
