Presuming that we have PTV get and set functions - it's inevitable they 
will come ;-) - then it's not really that hard. One simple method is to 
use an action handler; so it behaves in a similar way to the 
PageAction's menu. You could also route to a page with a local 
customization script, if it suits - I do this kind of thing for 
confirming changed email addresses and suchlike.

I like the idea of the profile page being used for member-related data 
that is stored as PTVs.

Yup, I've already incorporated this technique - thanks, Pm - and it's 
cool for saving real estate, but sometimes you want all the options 
presented out there in the open.
