[boost] Using multiple versions of Boost

Hello, Assume that you have multiple developers developing plugins for a commercial package and that we recently deployed boost 1.34 to our facility. For some informed developers, they will switch over to 1.34 whereas others might not know and stick with 1.33.1 or even 1.32. Now imagine loading in all these plugins into the 3rd party app, wouldn't there be some sort of symbol problems especially with boost run-time libraries (take the regex library for example) ?? Does anyone have suggestions on handling this? A typical way we solve versioning our open source libraries is to add a namespace to it. eg. SomeLibrary::v1_33_1 (although we never did attempt to fiddle around with boost). Any other ideas? Thanks!
