I am somewhat new to DotNetNuke. I've known about it for years, but only recently started to actually use it. I've got it installed and configured for 3 different customers and I really like what I see so far.

I have a new customer that has outlined very specific requirements for an entire portal / community site. Looking at his laundry list of preferred open source applications, I am not quite sure that there is a proper combination of DNN modules to fit the bill.

One of my primary concerns is integration. With his list of products, I think it would be very hard to integrate them all into a single unified system for single sign on, authorization, look-and-feel, etc. That's why I am leaning toward DotNetNuke as the primary platform, if this can even be pulled off.

Here are the various systems he would like to use:

• LifeRay Portal Server (Main Portal)
• Wengo
  (Chat Client)
• Epresence Video and Web Conferencing
• Moodle (LMS)
• Sugar CRM
• ICECUBE Social Networking App
• Asterisk Call In Conferencing
• OpenFire Jabber Server
• Alfresco Content Manager

Wow! Anyone know where to start?

Joel,

ask your clients to list the functions he needs, not the applications he has checked out. AFAIK there is no system, which can combine all the applications without major development e.g. for single sign on and administration of this couple of applications will become a nightmare for him. Next have a look at DNN modules, which cover some of those functionality and implement remaining functions in custom modules.
