It's been fully understood that unlimited plans are not fully unlimited(I should have mentioned this).

"to retain our current customers from jumping ship to other hosts who were offering unlimited."
I'm worried no customers will come aboard because I don't offer a competitive plan. I'm also afraid of selling an unlimited plan but not show unlimited resources, people will leave.

My Father reviewed the question and advised me on a better way to ask. Could you offer an "uncapped" reseller plan?(It sounds less useful that way)

Having bought unlimited plans and dedicated servers before, you can set the storage amount of a package to '0' and when you log into cPanel you will see the infinity symbol. My question was more towards aesthetics, then physical space. Up until recently I did have a dedicated server in the US but the collo. fees were getting out of hand.

Programming is a HUGE part of my life. I know Java, C++, Objective-C, PHP, and HTML/CSS. So security an such is not a large issue with me.
