I have a small balance in my Oanda account so I downloaded this thing and gave it a try a few minutes ago… I guess I’m not that risk averse.
They don’t seem all that far along. For example, it’s hard to find the download link or understand the fact they use two logins. One login for their site and a different login when you want to use the platform to connect to Oanda.
However, warning, don’t start running the program on your account if you have any active trades open. It appears that it is set up by default (as of today anyway) to apply what it calls soft limits. Basically, there is a chance it will close trades on you… as it has done for me. Once you have a square account you could then start using their platform and get used to it.
It also reports errors that apparently aren’t errors depending on the version of .NET that you may have installed on your PC. I saw this on their help/forums prior to download and noticed it giving errors while it was shutting my orders and taking profits for me… 
Anyway, all that said, I like the idea of having a metatrader bridge (which I haven’t tried) and/or having alternate access to API trading. As said above, I am not worried in the least about Oanda’s trading practices – people are always trying to blame their poor skills on their brokers (though I suppose some brokers do have issues).
