I have checked that. As I am using the original RPM packets provided by Adobe 
the files are located in /usr/local/Adobe/Acrobat7.0/Reader/intellinux and a

chcon -t textrel_shlib_t \
	/usr/local/Adobe/Acrobat7.0/Reader/intellinux/lib/*.so

seems to be sufficient to run acroread and also use the plugin in Firefox. 
BTW, what are SPPlugins and plug_ins for?

However, thank you Paul for providing this more customized solution. I assume, 
that I only have to change the type context of the libraries distributed with 
the Cisco VPN client accordingly to run it with a "fully" enabled selinux.
