I believe you are right about direct sales, but there are several third party sales options and each of those are "commission" only type of deals.  EDIG's margin is less (similar to Mezzo), but they have more boots on the streets.  The results are unknown.

My guess (WAG) is EDIG has had contact with multiple non-IFE buyers with no deals thus far.  Will they catch one in the near future?  Who knows?
