Magnification for PDAs and Smartphones using RDesktop

Question

If I've got some Native Windows App (i.e. Delphi) and I'm having a lot of end users running it on things like the Nokia N800 connected to a windows terminal server using RDesktop.

Some of the things on the screen are very hard to see, but I don't want to have some weird magnification of the whole screen because the resolution on those Nokia devices is really pretty adequate.

Anyway, what I'm wondering is how you would approach a problem like this, I see in my list of related questions that there is Windows Magnification API, is that good for Win32 or just .NET? Is it too clunky to just increase the relative size of the button or label nearest to the stylus or finger or mouse on the screen. Are there 3rd party API's for this kind of Hi-jinx?
