I've just stumbled upon the FT230x chip, and this thread. I'm replying to it instead of starting a new one since it doesn't seem too old....
The chip looks like it will be easy to use in a circuit; have you had any problems?
I'm also interested in where you're getting them. I checked DigiKey, Mouser, Newark and Octopart; nobody seems to have it in stock. Any other leads?
Thanks in advance.
