bearbull, You're probably stating something that many of us know already (or at least we 'think' we know). There may be consultants selling shares which were issued in the past. Also, revs haven't been gangbusters and there may be shares overhanging which were used to fund operations.
IMO, if you truly are interested in this stock... then sit tight. If you're mainly looking for a quick runup and flip, then it'll take bigger news than this. The long struggle (revenue-wise) has made it so that some serious news needs to come out before this stock gets "hot" again. Not a lot of liquidity on this one right now.
Anyone else have contrary thoughts to what I just posted? I'd like to hear if you do.
