Yes, the 4000 number was used at least once. However, that was a long time ago.
I beleive the best guess was OZ's $10M-$12M in revs based on current burn rate and his read of the financials (corrections welcome). It certainly depends on what percentage is for higher margin services as well.
With a little luck and Willy's hard work, EDIG should be much closer at the end of this fiscal year. He has done what he said he would do. I'm betting fiscal 2009 is profitable, but I'm dumb as a rock and I own a shipload of EDIG -- plus a healthy dose of that "P" company -- so nobody should ever act upon my drivel.
