Also, if you look at the stats you'll see that although Counterparty has greater than 80% of the transaction volume among Bitcoin blockchain projects, the market capitalization of Maidsafe (on Omni/Mastercoin) is greater than all Counterparty projects combined.

You'd probably be surprised how many transactions can be associated with "send to many" actions, such as the distribution of LTBcoins.
