Which is it and is there some demo/test version available? Are there any
specs available about how it perfomrs the virtual input?

Did you try to get the SYSWMEVENT and checked, whether it occured on
performing some input with the virtual keyboard? Maybe the virtual
keyboard uses a different Win32 event type with extra payload describing
the key:
events = pygame.event.get ()
for event in events:
if event.type == pygame.SYSWMEVENT:
print event
....

It talks directly to the Win32 application/window message queue and gets
its events from there, so anything arriving in the message queue will
find its way into the SDL (and thus) pygame event handling queue, usually.

Are we talking about pygame or pygame reloaded? Both have a different
kind of API (though the event handling does not differ much).
Besides that, neither pygame nor pygame reloaded support SDL 1.3.
