Trif,
You can buy airlayer lychees from ebay, when they are in season usually in the mid to late spring. There are a couple good ebay sellers of airlayer lychee trees.
Saxonfig,
I am in zone 10a, in Orange County, CA. So I guess you can say its a frost free great grow zone. However, I see no reason any of you guys could not grow and fruit this in a sunny south facing window/indoor location. As you can see, I was able to make it flower nicely in a 18 gal tote container. Also the humidity is less then optimal most of the year in my location (20-40% humidity on average day and night).
