Hi Eric,
This is a great question and I'm happy to connect with you as I'm also part of a somewhat 'locationnless' that is trying to apply ABCD. Mine is called Uprise Art Collective and is a network of artists of all genres (including music) in Sarasota, FL. Our groups seem to have a similar 'glue' which is the love of our creative craft/outlet and the desire to pursue that love in the company of others.
Regarding your question, I'd say definitely YES! You can apply ABCD within an organization without being tied to one location.
I'd highly recommend checking out Deb Puntenney's book (which you can get via pdf here:http://www.abcdinstitute.org/docs/CFWText.pdf). It's all about how to apply ABCD in organizations.
And in my OWN experience, I've found it's about making time and getting others in your group excited about finding out what the assets, gifts, talents and interests of your members are and then figuring out how to use those to get where you're trying to go as an organization. And sometimes the interests of members can help determine where you want to go!
One thing you could do is team up with others in your group who resonate with the ABCD philosophy and discuss how you might go about using it in your group. Much of the stories we hear and 'models' for applying ABCD came from just that 'formula' -- every group is different and local innovation is the heart and soul of ABCD. You will probably find it useful to undertake some kind of asset mapping process. I'd suggest two other publications that are my favorite for that:
A Guide to Capacity Inventories
http://www.abcdinstitute.org/docs/CapacityInventories(1).pdf
Discovering Community Power: A Guide to Mobilizing Local Assets and Your Organizations Capacity
http://www.abcdinstitute.org/docs/kelloggabcd.pdf
Is that helpful?
Please keep us posted on your adventures in this!
