No there is no other open source software that does what ookala-mcf can do 
with the Dreamcolor.  Apps like ookala-mcf can be used to calibrate the 
internal LUTs of the display and this requires that programmer need to know 
the protocols used to do this (IE. what messages are sent to and come back 
from the monitor during this process) and this information is only available 
for a few monitors.  In fact the only monitors that I have seen thins info for 
are the Dreamcolor and only because it is in the ookala-mcf code.  Other 
monitor manufactures will not release this information so that means that it 
is nearly impossible to develop an app like ookala-mcf that works for a wide 
range of monitors,  This makes a project like this very unattractive to open 
source developers.

The ookala-mcf project was basically still born.  HP through a tar ball up on 
SourceForge and and more or less walked away from it.  They never even 
bothered to setup a source code repository and did nothing to encourage a 
community to form around it.  This is all really sad since what is there is a 
very powerful frame work for creating a plug in system for color components 
for monitors that included a base set of plug ins.  But they did not or were 
unable to even convice X-Rite to make the libraries needed for the two 
measurement device plug ins readilly available.
