Maybe often used manufacture IDs, eg. Roland, Yamaha, should be excluded ;).

Using one output just for a synth that receives SysEx on real-time e.g. 
to control it's filters isn't a problem for standard MIDInterfaces too, 
but there's another issue. Not all Sequencers have an option to edit 
SysEx. If your device can't send e.g. SysEx for filters, but only 
receive such data, you're not able to use this functions. Nearly every 
sequencer is able to transform controllers, e.g. you sent 1 (modulation 
wheel) and transform it to 6 (Data Byte) for the receiving device.
