Wow... this is a really interesting way to look at these three products (WebEx, Spark, and Jabber). I've recently struggled to figure out Cisco's Collaboration strategy for these three products (and what I should be recommending to my company). We’re big WebEx and Jabber users today and I’ve been wondering what Spark brings to the table. Do we replace WebEx (actually CWMS) or Jabber with Spark? We have groups that use Jabber persistent chat rooms for some of the things Spark does, but I’m always leery of forcing an application into a use for which it’s not optimized.

Thanks for the alternate frame of reference!
