I downloaded your Windows client and am scanning it for viruses before I check it out. Will post my thoughts here when I've done so.

EDIT:

Both compressed and .exe files passed Virustotal checks with zero warning flags. Local scans showed the file to be clean.

I ran the Currenion sandboxed and it did not appear to create any unwanted or extraneous processes. I created a secret key and a throwaway login, and was able to see the inner workings of the wallet system.

Looks potentially pretty cool-- a hold-to-unlock system depending on whether you want to be a gateway, merchant, or market-maker/liquidity provider. Like a distributed Coingateway service.
