Telescopes are sold for $200 which include programmable positioning devices (2 axes obvioiusly). I suppose its just a reduction drive and the usual electro-mech-control stuff but it implies a high degree of angular resolution for cheap. Has anyone: 1. ever used the refractor type telescope tube

I presume most people have by now read Cringely's piece on hacked Linux for Linksys WRT54G (and clones): [...] It does VoIP, prioritizes traffic, has currently VPN pass-through and will do IPsec on future mesh-supporting firmware. You forgot to mention sometimes it'll stay up for as long as
