> Will this be sync IPC calls from the renderer to the browser?  That's ok, but it seems like it could be a lot of IPCs when moving the mouse quickly during a drag.  Isn't this how paste currently works (a sync IPC from the renderer to the browser to get the paste data)?

It's a sync IPC call. It is a lot of IPC calls, but getting the list of types is generally cheap. The expensive part is getting the data. I've tested it locally, and it doesn't /seem/ to cause problems.

An alternative approach we could take if we find that performance is an issue is populate the most commonly requested pieces of data (such as the types in the clipboard, for example) in advance rather than passing it by IPC.
