unlimited domains on reselling

Do you think it's possible to host unlimited domains on reselling as some companies have offered (hostgator, hostpebble, etc.)?
Have you ever tried that? 

No I prefer a dedicated server. Shared hosting is not that good especially when you have to host many sites

I think there is nothing as unlimited because we certainly will have a limited no of domains. By unlimited I think they mean any number of domains. I think they allow that

Sure, but for the reseller account unlimited domain quantity is the must, as having a hosting business withlimited domains availiable for being hosted makes no point in business at all.

@OP: If to make a recommendation I would name hostsvault.com as this company is really attractive host for starting a reseller business with!

couldnt you build you own server at home? dont really know about the costs

Unlimited domains at reseller acccount is the necessary feature, as havingh limitd amount of domains you are able to have limited amount of clients as well.

For quality reselling hostsvault.com is highly recommended.

Some shared hosting have limitation on amount of addon domain

You know dayana host offers that on their reselling and I do believe it's great.
That's not complicated at all.
Guess any decent company must offers that if they provide reseller services.
