Netsuite License Policy - Number of Users

Any chance of a "concurrent" user license license in the future at Netsuite?

We have morning part-time and evening part time employees with CSR roles and unfortunately we are paying for unique licenses for all of them even though they will never be concurrently logged into Netsuite at the same time.....
Same is true for some of our full time employees ... a few only log in for a couple hours a day or every few days.... yet again we are paying for unique licenses for each of them.

Since Netsuite knows who is currently logged in I would prefer a # based license fee structure that monitors total # of users logged in.  That way more employees could share a license pool at a company and spread the word of how Netsuite works to friends and business associates.
