One of the most appealing things to customers about open-source at large and drupal in particular is the "no vender lockin" argument.
This is thrown around by us as a drupal shop very often but I'd like to brainstorm and share "war stories" about how drupal projects "move" and change hands throughout the "drupalshop ecosystem" and why they move that way.
I think it's crucial to communicate how by applying best practices we can truly liberate our customers and give true substance to the "No vendor Lockin" cliche.
