S (Support Level): * Web-site forums (separate from cpanforum site) * Specialty newsgroups (hosted by developer), fits in w/mailing list * Public CVS or other version control system site * Bug database separate from rt.cpan.org * Some modules maintained in sourceforge (which has CVS and separate bug database)
L (Language Used): * Using Inline code in another language * Using XS code to interface with some other software or library which a user may or may not have * Using Filter or some other altered syntax in the language (e.g. Perl6 modules)
I (Interface Style) * As with Language Used, alterered syntax (e.g. Perl6)
P (Public License): * The module interfaces with a commercial application, even though the module itself may be restricted
I'm curious as to other module authors' thoughts on this. (Many apologies if this topic has been recently covered; I've been out of the loop on the module-authors list for a while.)
