Faking a serial port like that would be tricky in any language, but particularly tricky for a scripting language that isn't designed to run in driver space. Depending on the degree of control you have over the applications you may be able to write a Perl daemon that connects to the GPS serial port and provides pre-digested GPS information to applications.
