For sure, SubTCP is unfair and will not converge.  However, it was meant to 
operate in a TCP congestion region which is dominated by RTOs.  In this region, 
TCP is an exponential decrease, hyper-exponential increase algorithm which is 
even worse (as demonstrated by the Morris work).  While this small window 
situation may not be very common these days, it was mroe common back in 1997 
when it was proposed.  Results from the '96 olympic web server work by 
Balakrishnan et. al. showed a large number of TCP connections operating with 
small windows.
