Well, at the moment... no[cool]. And it depends on what you mean by 'older'. DDFI-2, for sure, DDFI-3, very plausible. Unfortunately the documentation on DDFI-1 is a bit sketcher than the newer ones and I don't have a tube frame at my disposal to test. So the short answer, likely yes. There is no reason that code couldn't be written to do everything that ECMSpy does (like viewing/resetting error codes, TPS reset, built in tests, and EEPROM flashing and back up, table modification). If I could get the assistance of someone more experienced with tuning there is no reason that real time updating of fuel maps based on logged data couldn't be done from the phone/tablet.
