I haven't really looked at the notify_isp.rb plugin (since I'm not a ruby 
guy) though I appreciate all contribs (thanks Nazar!).

I've been meaning to get a new DenyHosts release out (especially now that 
I finally released ReleaseForge 1.3 which I naturally use for all of the 
DenyHosts releases).  I'll add the plugin to the "plugins" directory such 
that it will be in the upcoming 2.7 release.

I don't think the sync server is the best place to launch the 
notify_isp.rb script from considering the sync server doesn't have all of 
the info that would make it useful for the ISPs to use (specifically, the 
line(s) in SECURE_LOG that document the attack which I believe the ruby 
plugin extracts from SECURE_LOG).

FWIW, DenyHosts 2.7 adds a SYNC_PLUGIN option but I wouldn't recommend 
using this plugin for that since it doesn't have the necessary 
SECURE_LOG entries either.
