You not going to achieve this using one key. First, you can safely assume
that your key or key parts will find their way to a keyserver. Once they are
on a keyserver, the IDs will once again be combined and viewable for all.

If you wish for different e-mail addresses to be visible for different
roles, then a separate key for each role is the correct model. It is also a
common practice among some users of ggp/pgp. The work key may have an
expiration date and/or be revoked if you change employment - datails you may
not wish to have cluttering your personal "home" key.

With few exceptions, there are no "good" and "bad" in key management. There
are practices that fit differing needs. There is a Yahoo! group, PGP-Basics,
 that you may also wish to join and ask your question. They field this type
of inquiry all the time. (
