More and more, large institutions (universities, companies, etc.) want MSI's. If there is a version for windows that is MSI, then we can get more adoption in those areas.

But why?  What benefits are there from it?  In my experience, there are only disadvantages in the MSI format. 

I don't think this might be best for 0.47, but is something to keep in mind. Personally I think it would be good if some group out there could setup up and provide some bodies to actually do the MSI. :-)

I've looked at code for MSI things and I think I could bone up on them enough to do one but I don't want to unless a serious reason for it.  I can only think of a couple of instances where open source apps have used MSI packaging... 7-Zip 64-bit is one instance... though I don't understand why - NSIS supports 64-bit just as well.  Hey, is there any Inkscapey goodness for 64-bit Windows?
