Well I'm certainly not going to let your qualification prevent me from flapping my lips!

If I have a large object inside zope (say for the sake of argument a one meg audio message) and it's requested by someone who's on a godawful link, which only gets a couple of Kbytes a second of bandwidth. Is Zope going to be inaccessible while that file is downloaded?

Nope. If you are using PCGI, the entire contents are poured into the PCGI process, which reads it all then trickles it back to the client. That is, PCGI buffers all I/O. I believe both ZopeHTTPServer (with threads turned on) and ZServer behave this way as well. --Paul
