(1) What is the status & plans for supporting "bitcoin:" URIs in the Satoshi client?  My understanding is that it currently creates URIs, but does not register itself with the OS to handle such links.  Is this accurate?  This seems like a very high-value feature, and I'd recommend that we consider it a priority -- I can't think of any other upgrade that can improve usability so dramatically on the desktop.

It is already implemented for Linux (Gnome) and Windows, but there is an issue with boost::ipc that crashed bitcoin at startup on windows, so it's temporarily disabled on Windows.
 
(2) I need to understand better what the intentions were behind "label=" and "message=".  The way I understand it is that Bitcoin-Qt uses and stores only address-labels, and no other transactional info is stored in the wallet.  As such, the "message=" field would be displayed to the user when a "bitcoin:" link is clicked, but that message wouldn't be saved anywhere.

Label is a label for the destination address, message is a freeform message describing the transaction.

I don't think the message is currently stored in the Satoshi client. That feature is somewhere on our way-too-long issue and todo list.

But I understand that you want to add transaction meta-data fields such as contact information, bought items, item prices?
