My suggestions included Trachelospermum jasminoides, known as star jasmine (or Confederate jasmine in the USA). This will survive quite happily in a big pot and as well as white fragrant flowers has the bonus of glossy evergreen leaves. Admittedly, it doesn't flower as freely in shade as it does in sun, but the screen of green leaves is worth having anyway.
Nicotiana is a must. I find N.affinis does well in pots and seems to be more snail-resistant than N. sylvestris. Adrian might also like to try the F1 Perfume series, which are smaller, but very reliable. The pale lime ones look good with white.
Lilies are a must and all seem to do well in pots. L. regale has a knockout perfume but in my experience is more susceptible to lily beetle. Perhaps Adrian could go on a lily beetle hunt of an evening, squishing the little red b****** while pretending they were a particularly uncooperative, late-filing contributor. Very therapeutic.
The new varieties of nemesia have wonderful scent. N ‘Wisley Vanilla’ makes a wonderful mound of ice-cream scented flowers. And although busy lizzies aren't scented, they are perfect for shade and good at providing pools of white at twilight. The 'New Guinea' ones have bigger flowers and more interesting foliage.

I think people often underestimate the importance of foliage in gardens in their feverish search for flowers. Personally, I'd have lots of hostas, and perhaps Japanese maples and ferns, which will all survive in pots. I'd probably have a fatsia, too, or a choisya, again to provide year-round evergreen interest. In my opinion, as you can see from the photograph of Philip's garden above, a lush green background is far more restful than a blank wall and offers a real sense of sanctuary from the world.
A water feature - perhaps one of those overflowing pot versions with moving water that won't allow mosquitoes or midges to breed - provides a restful background noise which distracts from traffic and aeroplanes. Here's the water feature in Philip's garden, which is simply a ceramic bowl with a wall spitter connected up to a pump. All the boring bits like pipes and wiring are hidden behind the surrounding pots of hosta and zantedeschia, and large cobbles.
Anyway, these are just off the top of my head ideas. What I'd like - and what Adrian wants - is lots and lots of suggestions. So get thinking - and commenting!
