Does it just slightly depend on java or is the whole package developed 
in java.

I generally prefer solutions based on C and C++ because of the 
performance advantage and they are nice and compact and can be packaged 
up into a nice executable  or  shared library.  I have had very bad 
experiences with Java and performance issues - even with JIT. It also 
requires a massive JRE to be running on the machine that consumes memory 
and cpu cycles like there is no tomorrow.  Java is a nice tool to 
replace cobol and to develop payroll and web applications, but I do not 
prefer it for core systems development.

Either way I would love to see and test your solution and thanks for 
making it available to the public.
