Aha, I was right! We switched away from IP reliance in the upcoming
1.0.8 release, as well as the newer 1.1 development release, see Rey's
comments below about the 1.0.x series:

It is addressed in 1.0.8, suggest you tell them to read my blog here:,com_jd-wp/Itemid,33/p,28/

Basically they will have an option to use session id generated from
only first 3 values of IP address instead of full IP, which should
alleviate such problems.  However full IP address (which is more
secure) is the default behaviour.

Note this makes session ids slightly less secure (not checking against
full IP), However the addition of mosConfig_secret and user agent info
will make the generated session id more secure than 1.0.7 and below.

Cross-posting as it is relevant info for the Joomla SIG.
