I'm currently looking into Sharepoint as a potential replacement for our company's bespoke, aging in-house built Intranet solution as it fills a lot of our requirements that have evolved over the years.
However, within our current intranet we have a WCF service that detects a user (we're a retail business, so in this case it would detect whether or not our user is at Head Office on the LAN or a Store on our WAN by IP as well as if the user is in a store, we detect which store it is without anybody having to login at any point) as we have two brands within our group and would be looking to replicate this functionality within Sharepoint.
The caveat is that some content is brand, area, region or store specific - not necessarily whole pages but sections of content on pages also. Is this something we could bring into Sharepoint in some way? If so, what would be the best way to do this?
