Does anyone have a business subscriber Internet connection? Is it worth it?

I just spoke with my ISP, and for an extra $40/mo I can get a static IP address with 100mbps that I can host my own website on. I have a virtualization server, and I've been thinking about hosting my own hobby-scale website for a while. I haven't had any luck finding rack hosting space that I'd feel comfortable using so I'm thinking about just going rogue, and operating solo. If I had a static IP address with a pipe that would allow me to host then all I'd need to do is stand up a server, register a domain, and point it at my IP address.

Other than the typical security risks, what do I need to worry about? Would the experience be worth it?

I have been looking for some software where I can brain dump all the things I need to remember on a constant basis so I can easily find it again in the future. A personal wiki basically. I am wondering what any of you tilderians are using?

The things I am looking for:

Absolute requirements:

• Open Source: I want to be in control of the data myself, and I want to be able to hack on it myself as the need arises.
• Self Hostable: Goes hand-in-hand with with open sourceness, I want the data to live on the server in my apartment, under my own control.
• An API of some sort so I can programmatically add/read/modify data.

Nice to haves:

• Revision history of some sort.
• Common/simple data format for easy backup and longevity.
• Web interface, with mobile compatibility.
• Lightweight as possible, so I can run it on a low powered server.

Does anything know anything like that?

Options I have heard of:

• TiddlyWiki
• DokuWiki
• MediaWiki
• ZIM
• Emacs with Org Mode
