I've also searched everywhere - Oracle Manuals, Metalink, Google, etc. Must be an undocumented feature!?!

Presentation layer resolves any differences in character set between client and server if different.
It ensures that information sent by the application layer of one system is readable by the application layer of another system. This includes keeping track of syntax and semantics of the data transferred between the client and server.
If necessary,the presentation layer translates between multiple data representation formats by using a common data format.

+ The various presentation options are JavaTTC, Two-Task Common (TTC), FTP, HTTP, GIOP(for IIOP), IMAP, POP, IM
APSSL (the last three for email) etc..

+ For EXTPROC and HS, the presentation is RO which means *Remote Ops*. That means RPC (remote procedure call). The Re
mote Procedure Call (RPC) protocol, documented in RFC 1831
