Serve two https hostnames from single node process & port

Is there a way to serve two https sites on the same port from node alone (i.e. without something like nginx)?

I'm using the https module, for which SSL options (e.g. key/cert/ca) are passed into createServer. I tried creating two https servers, each listening to a different hostname, and each with SSL options specific to that hostname:

require('https').createServer(sslOptsForFoo, expressApp).listen(443, 'foo.com');require('https').createServer(sslOptsForBar, expressApp).listen(443, 'bar.com');

But this throws an error:

Error: listen EADDRINUSE

Another idea is to create a single server rather than two, and to use different SSL options depending on the request's hostname, but I'm not sure if this is possible.
