We have this, bugzilla allows voting, you can vote once per bug/proposal  
(and you have 10 votes total you can distribute):

http://d.puremagic.com/issues/buglist.cgi?bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&query_format=advanced&votes=1&order=votes%2Cbug_id&query_based_on=

That is all the open bugs that have at least one vote, sorted by votes.

We also have a wiki where DIPs (D improvement proposals) can be created to  
flesh out ideas in a more formal fashion.  However, this system has no  
voting or really feedback, so I'd recommend using bugzilla or the  
newsgroups first.
