No. They are not officially being used for residentail installs.
In some areas, SWM-integrated Slimline dishes are used, but only for new installs with 4 or more receivers with one of them being an HD-DVR. These SWM-line dishes haven't been rolled out to the entire country yet, and, again, are only to be used in certain circumstances.
Those restrictions may be relaxed as volume production of the SWM-line dish increases, but since they will always cost more than a standard dish, there may always be some restrictions. Also, if you have any non-SWM receivers on your account, you won't get a SWM dish, as legacy receivers aren't supported.
