Using Dynamic CRM so many users can maintain contact list

[Peter S.]

Our company purchased CRM and it is going to used for some marketing
initiatives. We do have another need that I am wondering might be fufilled by
CRM. Our company has a defined list of our industry contacts that need to be
maintained by different groups in the company. Specific portions of this
contact data needs to be maintained by specific groups in the company. Does
CRM lend itself well to building a front end that users can log into to, to
update their specific areas of the contact list?

I saw that you can setup Sharepoint sites but I suppose I could do that with
a vanilla SQL database to some extent. I also saw the portal integration
accelerators and I am wondering if that might be something to piggyback on?
Anyone have any thoughts about how malleable CRM would be for this need would
be greatly appreciated.

BTW, the list would definitely factor into marketing initiatives so it would
be a proper home in the CRM environment.... The question is does CRM lend
itself to build a portal for solely maintaining and updating the list....
