[Zope] Is shared ZEO cache possible?

Hi, In the zope application that I am working on, there are nearly 40 ZEO clients. Restarting 40 ZEO clients is a time consuming process which takes hours - especially the creation of .zec files in each of the ZEO clients takes a lot of time. My doubt is whether it is possible to use one .zec file shared among all the ZEO clients? Thanks, Roopesh
