  Took a look.  Nice bit of code.

  Few comments/questions:

  Is there a html page out there that uses this, just to toss in as a sample?

  I plan on putting this in the utils directory in the server code.  That way 
autoconf can be used to fill in some of the fields so it just works with few 
changes.

  I note that there is a single file, stored in /tmp, that is used to track when 
players last downloaded.  My personal thought is that it would be easier to just 
create/touch a file in the player directory, and one could just use the last 
modified time on that file.  This does mean an extra file/inode used up in the 
filesystem, but I don't think that is that big a deal, and would seem to 
simplify the code.

  Related to this, it would be very easy for the server to create some other 
file to denote that the player is actually playing the game, and remove it when 
the player logs off.  Thus, the script could check for the existance of that 
file, and if it finds it, note some error.

  Now there could be stale data in this case if the server crash.  But I just 
envision the server creating that file unconditionally, so it wouldn't care.  It 
would just mean that you could get cases where you can't download the character 
after hte server crashed (if you were playing at that time) until you logged in 
and logged out.

  the other thing I'd do is change the output of the tar to just dump the data 
directly down the the connection instead of writing it to a tmp file first. 
That seems like it'd be more efficiently.  Also, potentially having a whole 
bunch of tar files in /tmp doesn't seem like a generally good idea.
