Full Round Actions as Two Standards

[Vendis]

I was looking into touch spell delivery with nonlethal damage, and I found this:

Start/Complete Full-Round Action

The “start full-round action” standard action lets you start undertaking a full-round action, which you can complete in the following round by using another standard action. You can't use this action to start or complete a full attack, charge, run, or withdraw.

I've never seen nor heard of this. It looks interesting, but at the moment, I can't come up with an overly useful application of it - after all, two standards does a lot more than one full-round.

Anyone have any good ideas with it?

Moving before casting a full-round action spell, to achieve Line of Effect before the casting. Example: Sorcerer flying up out of a fog cloud, before casting a Maximized Disintegrate.

Moving behind cover before casting a full-round action spell, so you won't be disrupted by an attack. Example: Stepping out of the room, before using Summon Monster to deliver some backup at the room entrance.

This is mainly used in situations in which you only gain a standard action but wish to do something that takes a full round action (like casting a summon monster spell while staggered).
