According to looprumors.com both Apple AND RealNetworks are wanting to purchase Roxio. I guess Realnetworks only has $300,000,000 in cash on hand so it looks like Apple shouldn't have much trouble winning if it really wants to.
I'd love to see Toast as part of standard Apple software. It's just one more complication in life that Mac OS lets you burn certain types of CDs in certain ways, and you need Toast to handle other situations. With Roxio, Apple could bundle in all that Toast does.
