Is anyone doing extragalactic supernova surveys in the IR windows?

It is now reasonably clear that Victorian scientists missed a
supernova in Sagittarius at the end of the 19th century; the
extinction towards the galactic centre in the visible is something
phenomenal (three papers I looked at suggest 25, 29 and 31 magnitudes,
but what's a factor 250 between astrophysicists?), so this is not
terribly surprising.

Presumably other galaxies have chunks of dust extinction just as the
Milky Way does, and I suspect it's not coincidental that the face-on
spirals seem to see supernovae more often than things like M31.

The normal solution to dust extinction is to work in the IR. Sag A is
routinely observed at 3.8um with adaptive optics on big telescopes;
but is there anyone who goes through the Catalogue of Nearby Galaxies
nightly looking for new K- or L-band sources?

(this is one of the few surveys for which LSST won't be the ideal
instrument, since its huge camera is a CCD array, so the longest
wavelength filter there is around 1um)
