Point-to-Point communication

[Richard_Harding@Playstation.sony.com]

I'm wondering how to do point-to-point, asynchronous communciation (just send
and receive blocks of quadlets) between two computers using lib1394raw?
Eventually, I imagine there existing an IP-over-IEEE1394 implementation, but in
the meantime how does one go about doing more basic communications between nodes
on the bus?

I guess my question really boils down to:  How does one map the CSR address
space into user/application data space?

FYI:
 In case anyone is interested in adaptor compatiblity. I've got a SIIG 3-Port
PCI (OHCI) adaptor working under Linux 2.3.99-pre3.

Thanks in advance.
