As someone that's worked as a producer in both cell phone gaming and console gaming, I'm going to need to bring some of your ideas back down to earth a bit.

First, unless the source for Homeworld itself (or a suitable clone) already exists, this project isn't getting off the ground unless a ton of Maemo programmers are huge Homeworld fans or you are hiring them.

Secondly, your timeline - in the best case scenario that Homeworld source is already available - is already WAY too aggressive. If that source code does not exist and you want to create your own clone specific for the N900, your timeline couldn't be achieved even with 50 programmers working on it 80 hours a week. It's completely unrealistic.

Porting is a very difficult proposition. It's not something that you can do in the snap of a finger like most game players seem to think when they hear the word "port". Often times the port ends up being much harder to achieve than the original product.

I want to see something like this achieved, but thinking that you'll have it all complete and finished with 10 people who are not being paid and working on their free time before the end of 2010 is delusional.
