Does the file just open with the "standard" file opening thing (which
is well-defined in Windows, but not in Linux)?

Unfortunately, you'd have to convert your diagrams by hand or through
some format like SVG to get them from Visio, as nobody's made a Visio
import filter yet.  The XML version should be amenable to it, though.

I'm sorry, but I'm not familiar with how Visio does it.

An easy thing to do is have a string property which contains the URL,
and a button property that, when activated, 'does something' with the
URL.  Now what that something is is an open question, possibly
invoking some appropriate mime-based library or program.

It could also be a object menu point that activates the something. 
URL should still be in properties (possibly even an URL list, if so
desired), and then the object menu contains and "Open" entry that uses
the URL to do whatever.

However, making it so that double-clicking the object activates the
URL is tricky, cause that interferes with the properties opening. 
There are a number of ways we could get around this, but we have to
tread carefully, as it's close to a core mechanism of Dia.
