keyboard remapping: help!

[mcb at oddjob.UUCP]

Does anyone know of a good way to remap a terminal (sun especially) to the
Dvorak layout?  The idea is simple: all you have to do is replace all b's
with x's, and so on.  The problem I'm having is that some programs seem to
take input directly from the terminal (so I can't pipe stdin to them through
a filter).

Please mail any ideas to me.  Thanks in advance,
