I had never really need to think through having different entry points and different perspectives / menu options for different guests. My BSVs made little use of guest access since all users were established by a central person & no use of Register User menu option. I had always thought of guest access as one dimensional ... one entry point for all guests.
Yes, is possible in AwareIM to do this in AwareIM.
For example, you have have a couple of different visual perspectives through which guests enter:
http://domainname.com:8080/AwareIM/logonGuest.aw?domain=BSVname&perspective=Register_New_User_A
http://domainname.com:8080/AwareIM/logonGuest.aw?domain=BSVname&perspective=Register_New_User_B
In my case, links likethese will be added to a different sections of a web page to enable the various entry points to the BSV.
