It makes alot of sense i have both DL1608 and DL32r with DC16 and the scalability of the system is in my oppinion one of its strongest assets , it is hovever a drag that you cant import a DL1608 show to DL32r but have to rebuild it when the clients band grow out off the DL1608. And freelancer just bring their iPad run and save their own shows ,and you can share if you are to take over a band
On some gigs it is practical to bring the DC16 get real faders and all , some times there is no space for it and a couple of linked iPads will do the job.
