The CoExplorer Project uses and co-explores different software to support the co-exploration.
The College of Exploration since 1991 has used Caucus Computer Conferencing Software as its main "online campus". While really robust and useful it is not entirely friendly to the mobile phone and new technologies. 
The Co-Explorer Project is using video extensively. We were one of the first to run webcasts since 1995. We have been using since it was first in Beta, now we have added Zoom, Facetime, Skype, and many others.
We have used wikis, and Mindjet, xmind, and other organizers. We are exploring the federated wiki development.
