From my experience they are just like Birch trees in that they only grow to one size. The rubber from them drips when the block is broken, it doesn't have to be tapped. So I think that any good tree farming program will do.
Hope this helps
MFR rubber trees drop rubber when they are destroyed so any program that harvests normal trees should work, though they may not offload the rubber automatically but that depends on the program.
