I've just received a new Raspberry Pi today and it's got 512Mb RAM. All the new Model B boards from 15th Oct 2012 have 512MB as standard.
Hopefully that solves the memory issue!
I certainly agree that getting it onto the R-Pi and into schools would be a wonderful idea.
If it's possible to squeeze Oolite into a Raspberry Pi I shall go straight off and build a mini Orac case for it

BTW I only just found out about Oolite via the Elite:Dangerous Kickstarter campaign.
Not played Elite since it came out (back as a collage student
