If you install two different applications with the same creator ID, the most recently installed one will overwrite the other during a hotsync. The creator ID is how the Palm differentiates between applications. (It doesn't use the file name or a digital signature).

What is the primary function of Creator ID's? When all else is put
aside, the most important thing that a Creator ID does is to pull
together the files belonging to an app into a single entity. Thus, when
one uses the Palm's "Delete" function to delete a no longer needed app,
the OS also deletes any additional files (databases, etc) which are
associated with the app by nature of having the same Creator ID.
This means that using a "random series of characters", or any
non-registered sequence, runs the risk - slight though it may be - that
when your test app is deleted it may also take out other unintended
files as well. This is not a problem if the only device the test app
is installed on is your own, but if you intend to distribute to even a
samll number of users I think using a registered ID is the only correct
way to go.

In my not-so-humble opinion, 1, 3 and 4 are all good solutions. While
the namespace of creator IDs is larger than any plausible number of
Palm applications ever, the number of memorable/pronounceable ID is
much smaller, so I'd rather IDs weren't registered for applications
that will never be published. If you go with #3, perhaps the best
option, your fellow developers will appreciate it if you pick something
forgettable.
For my throwaway apps that no one else will ever see, I use a random
unpronounceable combination of punctuation marks, such as '@#$%'.
