Making custom events scene-specific?

[Yi Liang Siew]

Hi all!

Lately I've been trying to port a small little PyQT tool I made over to 
XSI, but I'm running into a little problem: I've been trying to figure 
out a way I could get a python script to fire off upon loading of a 
specific scene (Ideally this would be the equivalent of the scriptNode 
in Maya).

I guess I could make a plugin that looks specifically for a custom event 
of the scene load and match it by name, then store that with my project, 
but I'm wondering if there is a more elegant solution already for this 
that I've overlooked.

Thanks!
