Hi kdelayed,
This plug-in may help you:
– It’s a One Click Plugin Updater.
Another alternative might be Manage WP which I use to manage all of my sites: https://managewp.com
I have about 12 sites so far and with just 1 click I update ALL of the plugins (and wordpress itself). Plus you can do 1 click installs and copies and backups etc very easily.
It’s not cheap though which can be stumbling block if the sites arn’t profitable.
Hope this helps!
Johnny
