Standups are awesome when done right... but unfortunately, given that my team works fairly independently, standups end up getting stretched because some member of the team prolongs his/her update to get a team opinion on either a design issue or a technical problem (or a product issue).
The simple way we time-box our stand ups is by planking [1] while giving standup updates. This ensures each person speaks for <1 min. All other issues are discussed at the end of the standup. Better core strength is an unintended benefit of the same! :-P
