Aida ProductionsUpdate:
considerations:
a) hacks and ddos attacks?
b) server lag?
c) downtime?
d) ISP permissions?
e) funding if decide to go VPS or paid server hosting?
a) Don't worry about this for now. Starting out small this won't be a problem unless you piss someone off. If you do get attacked, just restart your server and you'll be fine (trust me I've had my fair share of experience with this). Most DDoS attacks are very amateur script kiddies. But yes, you are at risk of a real attack, on your home network.. but I really wouldn't worry about this for now.
b) Depends on the download/upload speed + your hardware + your network configuration
c) Depends on you my friend.
d) Where are you hosting from/who's your ISP? Normally you really don't need to worry about this, especially for a Minecraft server. ISP's start caring when you're hosting a website or service with massive amounts of traffic (for example, hosting torrents from your home)
e) Setup donation ranks/items. or find a sponsorship somewhere (this will require a larger following/community, or a damn good idea/dream)
