Drivers and driven keys

Does XSI have the capability to set a driver for another obect ala the set driven key in Maya?

I think what you are looking for are Linked Parameters.

though we have linked parameters its limited compared to set driven keys in maya... but always there is the option of scripting for these stuffs...

Well perhaps if you explain the driven key concepts to a non-Maya user like me I could provide some more accurate information.

Driven key is basicaly a animcurve, wich instead of time is feed by the parameter of the driver. And outputs to whats driven.

Thei means you could do complex relationships that are non linear.

The example could be that a ball that rolls along a floor would raise a gate based on proximity of the object and when it gets further it again lowers down and in non liear fashion defined by the user.
