What pros and cons would there be >porting this server to native z/OS? These days you can't run z/OS without USS -- it's part and parcel of the operating system.

Hipersockets would apply when your software is (a) communicating with something outside the z/OS LPAR; (b) that resides on the same physical system (frame). Examples would include Linux instances running in other LPARs (with or without z/VM). Hope that helps! - - - - - Timothy F.
