I am a PhD student at the Technical University of Munich in Germany. My
main field of research are distributed virtual machines. I would like to
ask a few questions about the SquawkVM as from the latest paper 
about it I understand that Squawk supports Isolate migration.
I am especially interested in two details:
1. How does Squawk implement the checkpointing mentioned in the paper?
2. Where can I find the mentioned moveTo(IPAddress ip) method?
I had a quick look at the main repository  and the squawk-spot
repository but could not find any hints about checkpointing or moveTo().
Thanks for your help,
