Never seen that option before. But if you aren't 'doing anything' other than using transmission, it should be okay to keep the lid closed. But since the MBP sleeps after closing the lid, you will have to wake it up be inserting a USB key or clicking an external mouse. I'd suggest however that you don't keep the lid closed...maybe half closed to prevent dust and such.

Was chatting up with Grudge when the topic of Safari vs Firefox came up. I'm sure everyone knows how big fan of firefox our Dr.G is. Anyway, here's some points of Safari I've highlighted that I really can't do without. And this is Safari for Windows. On the mac there's much more.
- Resizable Text Fields
Resize text fields on any website: Just grab the corner and drag. (Oh if only the forum text boxes were a little bigger than the tiny ones they currently are)
- Private Browsing
Keep your online activities private with a single click. (Firefox can clear all private data, but this one let's you do your stuff while keeping your data intact)
- Inline Find
Search any text on any website with the integrated Find banner.(The neat little find thingie shows you at a glance all the words in the web page. Really nicely done)
- Merge all Windows. Cause while there are tabs, sometimes you open up separate windows...
- InstantSnapback feature. Just can't tell you how useful this is...
- And last but not the least, brings to me to something familiar in a weird place
The only thing that was missing, spellcheck has finally been added to the Windows end in the latest update:
