this looks like it would be enough, in combination with grab, and the pdata
functions to be able to pick an object, and get its properties. correct?+

presumably this should be a liblo compatible url, ie; osc.udp://127.0.0.1:5557/
with arg1 being the osc address and any further args being optional data.

well, you dont _need_ to have a different port (if yr using udp) ,.  just
depends on your opinions about feedbakc.

if the send-osc function uses a host/url, there isnt really a need for an
extra function, except for the convenience of doing something like
(osc-send-host ip port) which would return a url suitable as a 2nd arg to
send-osc (as above.. )

also, maybe osc-receive-port is a bit clearer, as constrast to osc-send.
what do you think?
