Sadly I don't know mod-able titles with FF, (though FF is pretty standardized in DirectInput, So I expect any title that uses DirectInput to be able to use it with ease). Pretty much is exactly how you would read an analog input, such a joystick throttle or x or y axis, but you actually send information to the device instead of reading it. You can also check status, reset states etc... I did look through OBSE list of input related functions and it's only reading the input from keyboard or mouse. ( though maybe those functions for keyboard work with standard DX input identifiers,then probably one can read a gamepad or joystick too :).. though is only "read" nothing about "sending" stuff ... Also I have tried finding an e-mail of the OBSE creators to ask them if it is planned in future versions of OBSE, but no luck, couldn't find the e-mails :D Do they browse these forums by any chance ?:)
