USB On-the-Go Go Go Go

There is an interesting article on CNET about a new USB standard called USB
On-the-Go. Apparently this new technology is an offshoot of USB2 and it can
remove the limitation of the master slave operation of normal USB devices,
where you need a Host PC (the Master) to talk with the peripherals (the
slaves). So using this, theoretically you can print using
your digital camera directly on your printer or maybe
connect two PDAs together to exchange some files. One thing that the
article doesn't mention though is the speed one can expect from such a
connection. If its as fast as USB2 then I think it can also act as the
replacement for NICs for interconnecting two PCs. But considering that
many wireless technologies like bluetooth offer similar opertational
capabilities,albeit they are much slower, can USB On-the-Go really be a success?

yes, very good feature, but why nobody use it ?
it's like firewire network. if i remember well, there is only one company which made available necessary softwares
It will be great if for example, home users can made all their computer or domotic stuff with only one or two interfaces. (not really the case in enterprise
The USB PCI controler cards can directly access memory, like many other PCI cards
The PCI interface in practice (not theory) is a bottle neck here. USB2/Firewire on the motherboard chipset is always going to be faster than on the PCI bus.
Where did the USB is processor bound rumor come from?
If I'm wrong, will somebody please supply a source so I can correct myself?
