Multiple Tascam us-1200 in Platinum

Been searching quite awhile now and can't come up with a definitive answer, today's SDOTD is a Tascam us-1200. I'm already running one, is it possible in Sonar Platinum on a PC to run two of them simultaneously? Most of what i've read says no-but that sometimes multiples of the same interface will work. And they say in Sonar there's the WDM option, which supposedly has low latency, but i wanted to see if anybody had experience in this on how much it changes. The 6-ins i have now works for me, but having the option of more would be nice on the rare occasion i get together with others to play and record. So this isn't essential, but adding to what i have at this cheap price is a more feasible option than dropping $250 on the 16x8 version.
Thanks!

Ok thanks. I plan to just use it for live stuff or big recordings where there will be a few of us at a time, and then can do overdubs later using just one of them in ASIO, so sounds like it should work for what i intend.

I run a Tascam US-1641 and a US-1800 over Asio4All (which is a wrapper
over WDM). This allows multiple interfaces.
 
I use this setup purely to record live bands, so the poor latency is not an issue.
 
It is true that the tracks recorded by the two interfaces are NOT in sync,
but tracks originating from each individual interface ARE in sync with each other.
 
So I add an identical offset to all tracks of one or other of the two interfaces
when I mixdown. Apart from this minor inconvenience, I have recorded up
to 28 tracks at a time with no problem.

In Windows, everything works with MME as its a Windows Multi Media Extension, Disadvantage is very poor latency and its 32 bit,

WDM should work but whether the drivers provide low latency for recording is another quetion.

ASIO 4 all has been found to cause problems with existing ASIO drivers that are installed.

For those running what we call a "Pro" system, ie. an audio device capable of running a low latency ASIO driver, the latest recommendation is to delete ASIO 4 all from the computer entirely. We've even found that running High Definition drivers for onboard sound cards like RealTek and nVidia can be a disrupting influence and uninstall those. Even deleting HDMI connections to your (TV) monitors has been found helpful in providing stability where nothing else would work.
