iwork.com - URL re-directing

I have this numbers document i want to share with some friends.

I also own a domain name: www.myname.com


what i want is to do the following:

myiworkdoc.myname.com

now if i upload the document as a "Public" file this works, as the link is generic (non unique), but if i do this i dont seem to have the ability for people to add comments and notes.

Therefore I guess i need to upload it as a shared file, with unique links, but im guessing this means i cant have a single re-directing URL.

Help anyone?

Thanks

 

dont think i made tis clear above.

the goal is to have a single url to send to my friends so they can all view the document easily.

but i also want each one to be able to add comments etc..


can they not each have apple logins, and i make it a private document and then have a single link that they have to login to their respective apple id accounts to see?
