As the boys said long ago,
technology moves FAST, and in the case of EDIG their tech has never been in any great demand by the tech markets.
As Robert Loest found out the hard way when he was forced to sell his $15/share investment for just $3/share, there were software solutions readily available to the tech markets that made EDIG's proprietary offerings obsolete. I doubt they've come up with anything new to put them back in the game, let alone in the active market arena.
