Integration Options

[SpeedStreet]

Hey all,

I've been hitting the books pretty hard, and I think I may be ready to tackle my first huge project. It will hopefully be a major addition to vBulletin and because of everything so many of you have done for me by providing your hacks and mods so freely, I will be doing the same.

That being said, I am currently in the mapping process and have started to think about vBulletin Integration. I want the product out of the box to work directly with vB. So my question to you is "What should integration consist of?" Here's my short list:

Usernames and Password session linkage (i.e. no replicating of database info, just strict linking)
User Permissions (w/ Options in the ACP)
Admin CP Moderation (if applicable)
Navigation Integration
Moderation Abilities through vb

I can't really think of much more than this. So please feel free to contribute if you have anything.

If you need to know sort of what it is I am developing, it will be a user based profile modification that should enhance the quality of life for certain vb sites....more than likely for many types of hobbies.

Thanks!
John
