I have been thinking much along the same lines, tho put the plans on hold
a year or so ago because the 1-wire stations were such a PITA to get hold
of. Do you know if the 1-wire rain guage is available anywhere sensible?

My thoughts for this was to run 1-wire over cat 5 to the patch panel in
the server room, then convert the 1-wire to RS232, plug the RS232 into the
spare rs232 port on my firewall, and then dump the data to a server in
amsterdam, as well as providing basic local graphs, (It has to be
transfered somewhere, the firewall has no hdd). 

The other hurdle I am trying to overcome is where to put the weather vane,
as it needs to go where there aren't going to be to much interferances
from the buildings...

Would be most interested to hear how your efforts progress.
