The saga of EDIG is not that different than PTSC. Both have had much hyped patents and plenty of naysayers.
As a very long term EDIG shareholder, please do plenty of DD before you plunk down money on this or any speculative penny stock.
IMO, EDIG's short term hopes are with their eVU closed end system to keep their continuing poor cash flow situation in check. I like their chances.
Long term pps involves IP licenses like PTSC with many of the same potential infringers. To date, EDIG has not announced any partnership with a credible sugar daddy legal team like PTSC's TPL connection. The jury is still out.
