I may not understand what you mean by "portable".

As far as I can remember the evolution of PGP, I think (but I am not sure) that the concept of a secure viewer is a PGP proprietary function built-in in their software. I shall not discuss whether TEMPEST attacks, when targeted to CRT or LCD displays pose a real threat to encryption users (who is the targeting agent? who are the targeted/chosen users?) because I have no expertise or even reasonable knowledge of the technological aspects of that issue. But if it is, in fact, a viable way to breach confidentiality, it is possible that GnuPG could consider to include an external secure viewer program in future developments. As a matter of fact, according to Werner's email, some work has already been done, and is included in the CVS.
