Yes, there is a psychological barrier at .10, and trading over the last few days would not support the idea of anyone buying more than 100K's of shares at the ask.
even if someone did, it would be a short term spike as sellers would push the price back down to the .10 range. I think in this case slow and steady wins the race, at least until the trial is over.
I had a 30K buy and a 20K buy the last two days, and the orders were always split up into two blocks. I think the trade today was 25K and 5K. Even though I put in the order as 30K, and it never showed up as a bid even though it took a while to fill. All done through ameritrade.
