Hi Cameron,
it is no problem to cc it to the list.

Short intro for the others:

what to do, when the tomcat is not started or responding

I did it this way, because my experience was/is, that all images of
osgeolive had the default xubuntu tomcat running from start - this
tomcat is used to run the 52°North SOS.
If the default tomcat will not be available in OSGeo live dvd 4.5 and
the following, I'll have to adjust the script of the 52°North SOS.
Regarding the flashing icon stuff, I need some hints and support, how to
do it or where to take it from.

Feel free to comment.

I'll be on the road until Friday, but will check my mails regularly.

Kind regards,
