if we are doing an async api, its redoing the api.

I find PGSSAPI very distasteful.

There is no way to add more input variables to ISC.

ISC have been extended to day, for example for NFS. you have to  
acquire a special NFS credentials, modify the credential to select  
what enctypes the kernel supports, and then call ISC. This doesn't  
work for credential when you talk to different servers that have  
diffrent properties, like TLS channel bindings.

I'm not worried about rekeying, if you want to tackle that we are  
redoing the whole gss-api model.
