Har!! While not a Q-lab (you have to be E-6 for that designation), we are a Colour Watch lab (thats one of the designations for C-41). Our machines use the SM chemistry packs, which means the machines mix the chemistry on board by drawing concentrates directly from the containers and mixing them with water in a sub tank. Nice system. No more chemical mixing, just drop a box onto the reciever of the machine and close the door. Where you notoce a problem is when you are setting up control references. No problem with C-41, the control factors are close to standard. The paper factors are another matter altogether. Where regular RA-4 gets a factor of .02 .03 -.01. as an example, the SM factors will be .10 .09 -.07 or some such. IOW, Kodak can't get SM-2 to work, so they are diddling the numbers to allow labs to pretend to be in control. It is a testament to the flexibility of the RA process that it works at all.
