Actually ISO/SC21/WG6 "OSI Session, Presentation and Common
Application Services" is Actively working on the standardization of 
a Remote Procedure Call which uses the OSI Stack (Presentation,
Session etc.).  This work is coordinated with the ODP one.

Moreover the OSF Distributed Computing Environment (DCE) Standardized
an environment composed of several components:

RPC, Security, Distributed File System, Thread, Time, Directory, and
PC integration

which were thought to be portable on several environment (not only Unix
OSF/1) and several communication protocols; it is now available on TCP-IP
and UDP-IP and is easily portable on OSI Transport (TP4 or TP2); it
should also be portable on OSI Presentation.

About DCE RPC it includes a Interface Definition Language (IDL), which
is a potential point of convergence between ISO and OSF/DCE work, and
a compiler to automatically generate application data structures and
run time support to completely hide the real communication mechanism
used.

This allows you to write your application masking the communication
stack and the to easily port it.

The DCE Developers' Kit is distributed to OSF members and now also
to third party; the first release will be shipped at the end of August
or beginning of September, snapshot 4 (i.e. 4rd pre-releases) is going
to be delivered very soon.
