Yes and no :). The most confusing part of all this is that nothing has
been set in stone, least of which the terminology. I believe Daniel is
just noting the desired functionality, which will likely be implemented
using "grabs". However, touch grabs may behave a little differently in
that it will be possible to have tentative, not-for-you-yet touch events
sent to multiple clients.
