Just a personal bias here, but I think one of the most important things someone new to this can do is to get a small paid hosting account with a good hosting company which has been around awhile, allows adult content, and is well-received by the Link List and TGP owners to whom they may be submitting.
Absolutely no reflection on you or your idea, P3rlPhr33k, but a lot of new webmasters have been hurt by having the wrong hosting, either trying to use free hosting or by choosing a host which somehow let them down and wound up costing them the loss of all their hard-earned submissions when the LLs and TGPs dropped all of their listings.
If this was just for development of site and concept ideas but not for submitting, that might be useful for some things, but since you mentioned wanting a link back and asked about how they'd submit from the same IP, that may not be what you're thinking.
If someone can't afford or is unwilling to invest the few dollars a month on an inexpensive paid virtual hosting account they really have very little chance of making more than beer money in this business today.
Just my 2 cents.
