AFAIK nothing's changed for setup.

I think some stuff is supported in hcrypto, but best to use OpenSSL. You can 
use ldd to verify it's linked.

They are wire compatible, though perhaps not all options may be supported. I've 
used MIT clients with Heimdal. The biggest issue is that the config options are 
completely disjoint. Also the MIT options are case sensitive and may not give 
you any error messages.
