One way you can do this is setting the post_type query variable before
the posts are retrieved, say at the "parse_query" action hook, by
doing something like set_query_var('group') or whatever.

One of the most popular plugins, Mark Jaquith's "Subscribe to
Comments," alters the comments table by adding a "comment_subscribe"
field, and the lead WP developers featured it on the WordPress Extend
page for months, so I would say there is not much of a taboo.
