Dear Computer Taxonomists,

First of all, I cannot help but say that I am delighted to see that 
*finally* there have started a serious discussion in this list regarding 
the future development of the DELTA system.

There *IS* an open source DELTA project underway since April, 2000. This 
is the "Free DELTA" initiative ( led by 
myself with some help of French and US volunteers. The project has 
progressed slowly - ironically, because up to now the "list members" of 
DELTA-L never mind to discuss and engage in it, depite my regular posts 
on this list. I of course cannot accept plainly such a statement as "the 
list members here might discuss how an open DELTA project should be 
run". The project is right now about to be embraced by a large Brazilian 
governmental scientific institution and fast progress is expected as a 
result. As an aside, I am glad to tell you that over the last ten years 
there has been a growing number of DELTA users in Brazil.

There are *plenty* of very sucessful open source projects underway all 
over the world - with GNU/Linux surely appearing foremost among them - 
and I fail to see *why* an open source DELTA should be different from 
this in any way.
