Well, the prefix was an idea to make the file platform-independent
without having to rewrite it.  i.e. if such code were in Circle today,
all the implementors would have to do is prepend 0x01020304 to their
existing files.  With network byte ordering, they would have to do
a pfile/rentfile wipe, or write special code to convert the entire
file.  Uck.

For sure.  But unless *you* put ASCII playerfiles into the Circle
distribution, there will never be a standard that everyone can work
with.  :)  Get cracking!  Hee hee.
