I havent bought the server yet (possible VPS) but i am thinking about using linux with apache and mono for asp.net support.

I don't know much about this. What packages can i use together to have a store with customer support? What i like is

1) A store to purchase one item (its digital). More may be possible but they are likely to be addons which need the first item. 2) Have the the store send messages to my app which will generate registration key and deliver the digital item. 3) Create an account for that customer on a support site used for tickets 4) A Forum. I'd like a private forum for customers and may want their account to be disabled when their product license has expired. 5) A mailing list. I like non customers be able to subscribe to a list and i'd like to know if any customers are on it so i can send different emails to each if desired.

Are there packages that make any of these easy? I dont mind writing glue code if i need to but i havent tried any stores, mailing list, ticket system but have installed a forum once long ago.

My mail server will likely be through google apps.
