I think an updated answer is called for. :)
When integrating studio strobes with speedlights, there are two things to consider. Whether you want more control than manual-only triggers give you for either the strobes and/or the speedlights, and how robust you want the triggers to be.
Are there OEM/3rd party triggers to command the studio strobe?
Some studio strobes are manufactured by companies that also make triggers specifically for that family of strobes. And in some cases (Profoto, Paul Buff, etc.) these triggers can offer you remote control over the studio strobe power levels, and the ability to sync at shutter speeds above x-sync. Because the integrated power control of the studio strobe has to be built into the strobe, it's unlikely that any 3rd-part triggers can offer this function. However. That same power control may not be available with any speedlights, just as TTL triggers for speedlights probably can't control power for the studio strobes. It may come down to a one-or-the-other side trigger. Say, Paul Buff Cybersyncs with a Cyber Commander or Profotos with Air Remote TTL, but manual-only control of a 580EXII. Or you could sandwich a TTL trigger into the OEM triggering scheme and use two systems simultaneously. Or you could control both your strobes and your TTL OEM speedlights using systems like RadioPopper's Jr2 triggers, or PocketWizard's TTL triggers with an AC-3 zone controller and appropriate strobe adapters. Or maybe you're getting the Godox Wistro bare-bulb system and FT-16s triggers for manual power control, a lot more power than a speedlight, and a lot less weight than a monolight. Or maybe, you really want TTL/HSS and integrated with both your speedlights and your studio strobe, so you're picking up a Phottix Indra and some Odin triggers.
3rd party manual trigger considerations
If you decide that you're happy walking up to any and all of your lights to make power adjustments, and manual triggers are OK for you, then any and all 3rd party triggers are liable to work equally as well as OEM triggers--and they may be easier to use to integrate the studio strobes with your speedlights, and it just comes down to reliability and cost. If you're doing pro work and need rock-solid reliability, then PocketWizard Plus units are liable to be worth looking at. Triggers, obviously, are many and varied which is why you came looking for an answer to this question, but this is also one area where the technology and feature sets move swiftly and models are always on the churn.
Looking at the original 2010-2011 answers here, nearly every one of the trigger models mentioned has been "refreshed" (PocketWizard came out with the PlusX, RadioPopper now has the Jr2, and the Cactus V5 and Yongnuo RF-603IIs are the latest cheapie manual triggers), and the cheap 3rd party TTL triggers (Phottix Odin, Pixel King, Yongnuo YN-622) have hit the scene. Over the next year or so, manual triggers with remote power control appear to be the coming thing. The recent release of the Cactus V6 triggers and RF60 speedlight, and announcement of the Yongnuo YN-560-TX transmitter for remote power control of a YN-560iii to be released this summer are probably just the beginning of this wave. In the few days since initially writing this answer, I've already had to update it for the RP Jr2; if you're reading this post-2014, possibly every model in this paragraph will have been refreshed.
This is one place where you can't expect someone to just hand you the answers; you'll have to do your own research to keep up with the times. Some great sites to use for this are:
If you do find other trigger recommendations--check the date on that recommendation. If it's more than a year or two old, I'd highly recommend doing additional research. This is one area of camera technology that's moving very swiftly.
