[Zope] Simple way to obfuscate email addresses to foil spambots?

Does anyone have any suggestions as the best way to, within Zope, obfuscate email addresses such that, when passed an email, a script obfuscates it from being picked up by email-address collecting robots? Or any other creative anti-spam tricks.. I work at an educational nonprofit and our spam load seems to be increasing exponentially.. Thank you, Chris
