[Taxacom] chimp-human interbreeding & fuzzy origins?

When I first read this press release in the local newspaper, several possibly naive questions popped into my head:
(1) are humans and chimpanzees at all interfertile today?
(2) if the Toumai skull, which is said to combine features of both humans and chimpanzees, precedes the definitive human-chimp split, then are some of the features unique to modern chimpanzees apomorphic relative to homologous character-states in humans? -- as much of a blow to our egos as this might be ;^)
(3) and if so, are some of those plesiomorphies of humans symplesiomorphic with the states in gorillas and orang-utans?
Forgive me for gulping at the term "fuzzy origins." Just thinking what a fundamentalist preacher could do with that.

Comparisons of the chimp and human genomes are apparently suggesting
that they may have partially interbred for a million years after the
speciation process first began. Don't know the details, so not sure how
significant or accurate this analysis might be, but sounds like it be a case
of very fuzzy origins for both species:
