Maybe a bit of a late reply but life's been up and down of late, so this is the first time I've logged into actionscript.org for a while. Actually, that project is still upcoming for me. My ultimate choice though was to go with SmartFox Server as I am ultimately more interested in game design that I am in reproducing something as complex a socket server can potentially be. At some stage I may write a simple socket server as a proof of concept, but for now I've decided to go with SFS as it's price and quality appear quite decent. In response to your other question, no, I am an indie developer at this stage in terms of games I am developing.
Sorry I couldn't be of more help but I hope your game development process is already on the go, and going well.
