Profit by Proxy
Support is great and it's a lovely business to be in while the majority of people are not trained and the technology is too hard to use.
But in the end, support services that encompass excludable products like training and call in support is only ever going to be a small pie slice compared to the bigger economic footprint of all those internal knowledgeable employees.
Better start coming up with a more direct funding model if we want to seriously push the software forwards. We won't always have Oracle and Microsoft overpricing their services to make it easy for Red Hat and Novell to undercut them and still have money left over to show at R&D style core programming.
