Andrew,
Thank you for that. As you say it makes sense.
As regards your work on 10.04, I'm unfamiliar with the scope of that. Clearly the input of your company provides a massive amount to the Linuxmce community. While respecting your commercial interests it is very useful to the project as a whole the work that you contribute back. There are those of us, like me, who are neither developers nor potential customers. I know I'm hell bent on getting things to work for myself. Nevertheless, I'd be happy to contribute testing and feedback if that might be of any use to you.
I have concerns about the long term viability without substantial contributors and consequently I see the input of you and your organisation to be very important.
I do think a 10.4 version would be a very good idea. On the other hand I know that with limited developer contributions the direction of the project is determined by the knowledge and judgment of a small number of people. To prosper Linuxmce needs to be as open as possible, the documentation (for users and developers needs a lot more contributors, and the project needs sufficient momentum to provide version development within reasonable timeframes.
Currently I'm cutting up lexan and making holes in order to build a custom case for my centrally mounted motherboards (A Tyan atom for the core and three ASUS atom ions as MD's). Over the next month or so I will be in more of a position to contribute. From a base of absolutely no knowledge unfortunately.
