I'm afraid I can't agree with you because, as we are speaking about mobile devices and not pc's, hardware agnostic just does not cut it for the following reasons:

• This community exists because the members of it love their devices use them every day and develop on them for their own amusement and use and to be useful to others. People won't go develop apps on a vm for an imaginary MeeGo device which they don't even own, to be able to look at (and use) the fruits of their efforts.
  
• Installing oses on a phone is not trivial and requires many man-hours of work. See NitDroid for example. Hardware agnostic approach means that every dev will try to port the os on the device of his preference and in the end we will have a dosen alpha stage unusable ports which brings me back to point 1
  
• No new developers will come whatsoever. New people here come by buying their new device. Very very few do it the way around.
  
• We have no product. We can't build a website and say "Download Now", it will be a series of wiki pages explaining the ways one can try our software on a vm or some lucky devices. If Intel is unable to push the product in the manufacturers I fear that our contribution will not be very helpful to attract them. As a matter of fact most of the work done on maemo.org projects is interface-related and manufacturers prefer to differentiate using their own proprietary ui's. Especially cordia looks just like maemo (which is directly connected to nokia and maybe to the eyes of some to a failed product, and there may be even patents protecting the design) so no other phone company will be willing to use it. I don't mean to say that it is an obsolete ui, I think it's the best mobile ui in the wild, but marketing wise is probably a no-go for other manufacturers.
