SPI portability

[<mongoose magic shiman com>]

  Looking at the SPI C bindings, SPI seems abstract enough to work with
almost any GUI, except for one line I noticed:

void
SPI_event_main (boolean isGNOMEApp);

what is this function meant to do? Is SPI going to be tied to Gnome in
someway?

If the SPI is designed to work with any GUI then ATs would only have to be
written to access one interface, SPI. It looks as though SPI is based off
of JAA, a very different interface, so couldn't this be plausible? Thanks.
