Welcome
Welcome to the VMware Storage Blog, a blog dedicated to all aspects of storage in the virtual environment.
We get a lot of questions about Storage Architecture in VMware Virtual Infrastructure. It is a complex topic with many options and design trade-offs to consider. In this blog we will attempt to demystify the topic. Please let us know how we are doing! Thanks.
One topic to consider posting on is a detailed discussion of how ESX multipathing works. This is fundamental since any storage has to interact with hypervisor MP code.

Scott - welcome, and it's a rich, rich topic.
As a newcomer, it's always nice to have a deep list of "todo topics" so you don't dry up :-)
I've found the topics of VMFS meta data updates/and locking always need more elucidation with customer after customer. Multipathing today and tomorrow (like Krishna's comment) - and on FC, iSCSI in guest, iSCSI at vmkernel, NFS, as they are all different. SRM's API model as a framework for storage interaction. Add to that on the interaction between server-layer virtualization and storage virtualization (if there is any - my opinion is that there isn't intrinsically). This last one is under furious debate here: http://www.virtualization.info/2008/07/storage-virtualization-doesnt-exist.html. VMware's view on protocols is always welcome as well.
