Re: Interfacing With Ethernet

["matt_miles_uk" <m_miles@xxxxxxxxxxxxxxxx>]

sounds good... ethernet enabling a temperature sensor (quasar=20
electronics etc) would be useful...  I'm sure other folks have MANY=20
ideas of useful applications - getting a poll of interested people=20
and more importantly how much they are willing to spend per unit=20
would be a good start.  After that photos or video of a prototype=20
unit doing 'stuff' would be great.
