AFAIK smoke.exe can be used to run MSI validation outside of light.exe as of WiX v3.0 -> http://installing.blogspot.com/2006/04/msi-validation-in-wix.html

I'll try this with wix3.5 on our master build tonight. I'm sure there is a way to run the validation separately (i.e. outside of linking) - I'll check the documentation. We'll want to run validation as a separate/asynchronous process that doesn't impact build timeframes.
