I choose # 3
POET still doesn't have a party that's interested enough to get that involved.
YET!
Any Potential PDA's are waiting to see IF POET can get to the 100nm. 200nm is good and they have identified the path to get to the 100nm requirement ( in NR). I believe this to be a pre-requisite before negotiations can continue..
From the NR: The 100-nm goal is matched to the state-of-the-art commercial III-V foundry capabilities and will demonstrate the greater than 50x speed improvement together with lower power consumption by a factor ranging from 4 to 10 depending on the application as compared to silicon at smaller nodes.
