Since IDETalk is part of Demetra, i'm think that Code Review is very significant feature and will be nice to have it in Demetra.
For example, there are two developers. The developer, who currently fix Bug #1 - named as Max, and developer who curently fix Bug #2 - call him Mike for example :)
Then Max's fix done, his press Ctrl+K (commit changes), and check 'Send for Review to...', press "...", and choose Mike as person who will check Max's fix. Then Max press Commit.
After Max commit, Mike recieved alert with Code Pointers (regions and files that changed Max). Mike quickly check this and close Alarm with "Ok" or "Problem".
The same way, Mike can send commit changes to Max on review.
"Changesets to Review" can be view by reviewer. For example, everyone can see that Max's IDEA is have N pending reviews, M success reviews and P rejected reviews.
