Towards a Greasemonkey Script Which Would Automatically Click "Update Conversation" in Gmail

Most of my day I spend watching ticket updates via email. Google Mail (Gmail) has nice threading, so I can look at a conversation and expand/contract them, but if I send an email from the ticketing system, or someone in the conversation sends a reply, it adds a little link at the bottom that says "Update Conversation". Pretty handy, but there has never been time when I wanted to not update the conversation. This is a waste of time and a waste of a click: I should be able to have the conversation update in real time, much like Google Reader updates.
