Hi
There are many distros out ther in the market place at the moment.
Turbo Linux, Ubuntu, Slackware, bsd, Gentoo, Lindows, Knoppix, Mandrake etc.
Each distro has its following. Some are big in the US, some are big in the UK, some are big in Asia etc. But each linux has it's quirks and differences and development cycles.
If I were a software developer it may imaginabiley be difficult to keep up with all the distros and develop a plane to support them all. Samsung Contact while it was arround supported many more distros than Scalix does. However Samsung Contact made no money so is not around any more. Supporting many distros is just fine untill you need to develop the next release of your software. Then the testing for each release on each distro and regression testing becomes a huge barrier to getting error free code out in the market place.
Althought some distros are growing in popularity for many and varied reasons, for most of the people who use distros Other that RHEL, SUSE & Xandros they do that because the main attracting of the distro they use has some particular percieved advantage and mostly because it is FREE. Although supporting a great number of distros may be cool it would lead to more bugs in the Scalix code, much longer release cycles and a hugh increase in the size of the team of engineers developing Scalix.
An increase in the development team must be funded. Would this in general be funded by people who wish to use a distro which is FREE.
In genral people who by one of the main distros and pay for it do so because they value the certification and support options that come with their distros. These people/companies also value their IT investment and see it as a critical part of their business. In general they want support and are willing to pay for it.
Scalix produces a community version and instructions for installing the product on other platforms via there non supported wiki. People are free to chose whatever distro they want but there may be issues.
Many other software vendors have gone down the same path for the same reasons
Here is a snippet from the Ubuntu forum re Oracle
