Theres a couple of things that give me hope that MeeGo will work on the N900.

1. Go to http://www.meego.com theres a bloody N900 on the front page

2. The argument that it requires multitouch is probably wrong because according to the website MeeGo is made to work on Netbooks, and most netbooks do not have multitouch. Multitouch on a netbook would be awkward in the middle of a coffee shop or in class so making it a required feature seems unlikely.

Just my two cents, I've been wrong before. Here's hoping!
