No code was reused. Just Jean-Marc's artwork. Plan was to port LibEtPan in Windows and replace current email engine during Beta, but.. you know.. dead.
Why is it dead. The Sparrow team won't work on it any more... but they weren't going to work on the Windows version anyway. If you were writing it, why not keep doing so?
Obviously you might have to change the artwork, since that belongs to google now. Otherwise, it sounds like this is just an email client that YOU wrote.
