Why do you say that Novell is not so interested (I'm curious)?  I would say that they most certainly are.  ICEcore is the foundation for their Team + Conference product which is in the growth category of collaboration software (growing at like 40% annually).  Do to the size and growth of this segment, Novell is very likely to continue working with ICEcore for quite some time.  But ICEcore should continue to grow and gather other development partners and contributors so that Novell's decision to continue working on ICEcore would be inconsequential.  Open source is about lots of people coming together to make a better product not just one company.  When ICEcore was open sourced by SiteScape the very purpose was to make ICEcore a better product through community contribution.  In fact if I had to pick a singular goal that is important to ICEcore, it would be to expand it's contributor base beyond what it is today and get developers excited about working on a new paradigm for collaboration in the enterprise :-)  P.S.  I am curious as to why you say Novell is not interested.
