but the investment community has not shown any interest

about what you have all been discussing

Notwithstanding this being an OTCBB stock, serious investment is about predictability and to date the major revenue source has been hit or miss. There is no way of predicting what, if any, licences will be signed in any given quarter or the value. Once licensing improves, possibly as a direct consequence of the recertification of the '336, and the share price starts to increase, this will generate some interest.

PDSG is different in that once contracts start, they are usually for a period of years and one can start to predict potential revenue from upgrades and servicing etc..

As ever, it is still a wait and see what happens next situation..
