I would like to donate some stuff to seam:
1. A component that converts strings into (hexa)decimal html entities.
2. A tag to use this obfuscator (mainly a shortcut for h:outputText escape="false" ...).
3. A mathematical captcha that asks for the solutions of simple equations (like they use at jroller). The equation can be obuscated with the tag described at 2..
4. A tag to obfuscate email addresses (see [url]http://www.seowebsitepromotion.com/obfuscate_email.asp[/url] for more details).
Would be great if you include it in 1.3
