I hope this isn't too late. But there are pc plugin cards that would not only replace the DMM, but provide the switching channels you need. Signametrics makes a SM2044 that is a multifunction DMM. This DMM does all the basic measurements, but also does Frequency, LCR, and will provide voltage and current source function.
The SM4042 is a scanner card that will provide 40 differential channels, and upto 80 single-ended channels. Also, the DMM and Scanner can be synchronized to permit a fully automatic scan of the test points. But, there is support for VisualBasic, C++ and other languages. Let me know if I can provide some example programs.
Let me know if I can help further.
