Two Different Web Sites/hosts...use Same Domain?

Alright so like the topic said I want to be able to have two different sites with the same name. I am signing up to become a reseller but all I get is a store and I don't get any web space and what not. I want to be able to use that though for my hosting site and also be able to have it go to my design site and forum on Trap17. Is there anyway I can do that? Have two subdomains one for design and one for hosting? I figured I could use a redirection if I can't so when you type in the url for my host it goes to the sit but then the url will change and people will think it's not the same site.

May be I have difficulties in getting the real sense of your problem. Can you please clarify?
Anyways if you have a hosting space, you can put multiple domains there.
And as far as re-directing is concerned, there are java scripts available for free and they even can cloak your real address.(i.e. they can show www.yourdomain.com all the time in the address bar.)
Tell me if it's not clear.

Also, can you make it more clear if its a redirect of some sort. Or if you planning to get a mirror of the website.
