Disclaimer: I work on Route 53.
You can ALIAS to record sets within your own zone too, which can contain any arbitrary IP. This is useful when composing routing types (e.g. weighted plus latency). But we don't support ALIASing to record sets hosted on other DNS providers.
It is possible to ALIAS to a CloudFront distribution though, and that CloudFront distribution can in turn use any arbitrary name as its origin. It's also possible to ALIAS to an S3 bucket, which can be configured with a redirect to any name of your choice.
Remote DNS-level ALIAS is something that we're always considering, and we're interested in feedback. If we support it, it's unlikely our 100% availability SLA will apply, that there may be inter-operability issues with CDNs (though we recently announced our support for edns-client-subnet: http://aws.typepad.com/aws/2014/04/improved-cloudfront-performance-with-edns-client-subnet-support.html http://aws.typepad.com/aws/2014/04/improved-cloudfront-perfo...) and incompatibilities with our future DNSSEC support.
