I'm not alone
Two mega-uber value readers write in with completely different experiences of Google's IP VPN. One, at VON in Boston, downloaded it but couldn't connect. The other, in Germany (ironically in Deutsche Telekom's headquarters in Bonn), downloaded and ran it in a public hotspot there with no problems.
UPDATE: I have subsequently heard from a few other mega-value readers that they are using it in various corners of Europe, and Om has gotten a lot of feedback confirming this thing is everywhere.
