Got some code in an Excel workbook.

User plans to save multiple copies of workbook.

The Good-Right-And-Holy-Path seems pretty clear: move said code to
a .XLA so any changes to same will be transparent across copies of the
workbook.

But I'm in Philadelphia PA, and now we've got the issue of user XYZ,
who opens the workbook for the first time - in London at 0400 EST.

I'd rather not have to engage in any hand holding and have the
workbook automagically create a link to my .XLA code repository.

Not a religious issue... but definately a nice-to-have.

Suggestions?
