Thanks for this post Zev.
I noticed the infiray site had gone down and grabbed the files from IA just the same as you did. Now the site is back online, I also noticed a lot of models and a lot of content has disappeared...
I'm very much not happy as the high-end Infiray model I have has been delisted which gives me concerns about support / firmware being unobtainium. Not good.

I also have grabbed if anyone needs:
android_irpt_tas_V1.5.0_S_build_31.apk
P2pro windows.exe
Xtherm windows.exe
