Hi Catharine,
I have published a document on Bulk edit methods, available here:
http://www.infopathdev.com/files/folders/web_methods/entry30374.aspx
This document is meant for developers who can create InfoPath forms to call these methods.
We have a Bulk Edit tool which has not been released yet; we're still on DBXL v2.2 Beta, so the tools are all "coming soon". :-)
If you'd be interested in such a tool, stay tuned for future info.
