jaiku is already open source, So , Now you have a free open source client from Google . Anybody needing a clone should use that
Using of open source is not an easy job for less code savvy people to keep it updated & to make the changes with the design. In my clones, I provide all the changes & features that client needs & client satisfaction is my main aim. When my client satisfied with the design than I feel that I have done the correct & right design.
