I thought why not ask them, so I've emailed and pointed them to this thread...contents of email:-

Dear Sir/Madam

Your announcement about Alien Dalvik has caused quite a stir on the talk.maemo forum this morning:- http://talk.maemo.org/showthread.php?t=69492
I notice that the youtube demo shows Alien Dalvik running in maemo on the N900 and I'd like to ask if you can confirm that it will be made available for this platform. I understand that you may be unwilling to confirm anything at this time but an indication of your intent would create a lot of goodwill toward you from all the users of the N900.

Thank you for your time

Sincerely

Dan *********

I'll let you know if I get a reponse
