Thanks to the developer. Works, (with big caveats) on a Nokia N8 with JoikuSpot Premium.
Notes - I can only access the internet via the browser - and that's it.
No email access and absolutely no in app internet access - so it's of very little use so far.
Has to be 'open' network - no security at all (yikes!)
Still, proves that in theory all limitations should be able to be lifted by some bright, enterprising person. I'd be happy to donate $10 to the first full adhoc app that works with email and apps too.
