But, in some ways I guess we are also talking
the Hen and Egg problem. Which of them did arrive in the first place

If You start out with a Solaris Port more people would consider it a solution for the Company/Case. But as long as Solaris does not offer that kind of option, nobody pays attetion to this great opportunity.
Well I just mean, that I understand the main interest comes from opensource interested guys like me. Most of them has adopted Linux as the primary OS for daily use. Since Solaris was opensourced one year ago it has not yet gained the same status as "the peoples" OS like Linux had.
It is growing in popularity, and after openening the source more and more start to download it for personal use. Also due to the fact, that in many companies it is a clear advantage to know Solaris as an IT proffesional, so students and young people starts to play with Solaris just to prepare themsleves and be ready for the "real life".
Solaris is mainly deployed in very proffessional environments so I find it a natural effect that You don't see many Solaris folks messing around here voting for Solaris and so on.
I know I sound a bit obstinate, but I really do believe Zimbra on Solaris would be the MS exchange killer everbody has been waiting for in a decade.
Since I am already involved in several projects I put the Solaris migration on hold myself, also because I am not experienced in packaging up Solaris software. But as soon as I get some space in my schedule I will happily grab the challenge myself.
Another way around, could be waiting for Solaris to run XEN dom0, and then deploy a Debian or Redhat as domU (guest OS) on it.
Only time will show which option wins the race
