[Air-l] Web-based research collaboratories and software?

Greetings, I wonder if anyone has used web-based research collaboratories and web-based collaborative research analysis software (e.g., something like Nudist or Qualrus online for multiple, geographically dispersed, researchers to use) and could direct me to relevant sites and perhaps share experiences. Thanks much, Doreen ****************************************************** Doreen Starke-Meyerring Associate Director, Centre for the Study and Teaching of Writing Assistant Professor, Rhetoric and Professional Communication Department of Integrated Studies in Education McGill University Montreal, Canada ******************************************************
