José-- You can use MySQL and Zope without a running ZEO. The relational database and the object-oriented database are independent. Zope can be configured to manage the ZODB directly or via ZEO.
You can also use the relational database as the store for the object-oriented database, replacing Data.fs. There has been some discussion of this on the web and in the archives, but I have no experience with this approach. I'm guessing that much of the discussion has been "proof of concept" and a relational store has not seen much use in production. I am interested in the performance trade-offs, but have not had time to experiment; Florent's ORM mappers sounds very interesting. Which version of Python and which version of Zope are you using? If you are having problems with a 2GB or greater Data.fs, check to be sure that your Python has been configured with large file support. Remember that the Python Zope uses may be different from that used elsewhere in the system.
