We tried this with GOK at an early stage and it was not satisfactory. 
It also clashed badly with StickyKeys.  It doesn't make sense to build
an onscreen keyboard and then not expect disabled users to try and use
it, and they will rightly complain if it conflicts with StickyKeys.

If you really are unwilling to turn on the global StickyKeys gconf key
while the onscreen keyboard is posted, or at least when the pointer is
inside it... (and I really do not understand why this would be a
problem) there is XKB ABI which you can use to change the latch/lock
status of individual modifier keys.  This should do exactly what you
want without making StickyKeys active for the physical keyboard.

google for XKBlib.pdf to find the XKB client manual, I believe it's
section 10.6 that has the relevant client APIs.
