Well there is some other stuff you can take into account.

for example lets say I have 3 subscribers behind the same IP address ...

 user A requests feed with ip addess 10.10.10.10 with agent=iTunes for windows
   -- > subscribers=1

 user a requests the feed again one hour later with itunes for windows
   -- > counted as the same user. subscribers=1

User B then 1 hour later requests feed with ip address 10.10.10.10
with agent = fireant for windows
  -- > Here we have to make a choice.  Do I count this as a new
subscriber assuming there are more than one people behind this
address, or do I count this as the same user assuming he has two
aggrigators installed.  Up to you, but in my system I count it as the
same user (I try to fall to the side of too strict).  So in my system
... counted as the same user subscribers=1  (I've just lumped two
people together perhaps)

User C then requests the feed from ip 10.10.10.10 with agent=fireant for Mac
 --> this time we see that it's a macintosh OS where as the last from
this IP was a windows install.
  --> Here I go ahead and make the assumption that this is in fact a
different user, as it is very cleraly a different machine (even though
its from the same IP)  subscribers=2


So as above, you'd have 3 users with the same IP address.  In my
system it would count them as 2 ...

I could have counted them as 3, but I made the rule that lumps some
together because I'd rather lose one here and there than gain 3
because of people like me who have Fireant, iTunes, and thunderbird
all pinging away.

IP address is important
HTTP user agent can also give you great information such as:
  * client application
  * client OS (sometimes)
  * number of users that this requests services (sometimes)
