Steve Walker has indeed proposed a potential scheme for software-based
key escrow, and the idea is being explored. It's much too early to
guess whether itwill turn out to be useful and if so, how it will
expressed. With respect to PEM, the design is supposed to be modular
enough to permit new algorithms to be added easily. Watch this space
for reports from time to time.

Does this indicate a new requirement for "new-PEM?" in need of
technical standardization? Steve Walker of TIS has made public
statements of a TIS software solution to law-enforcement. Do you intend
to bring the proposal in TIS products for standardization, or,
endorsement by the IETF? Is the Internet community your
intended market? Could this be, "new-PEM's" niche?
