Existing users, 
I use Teleport http://abyssoft.com/software/teleport/ which has been developed by an Apple Inc. programmer, I recall. It's free and works for me on my LAN. Maybe I am missing something, but I od not see what Desktop Transporter does for $30 that Teleport does for nowt.
If the developer would like to come back on that with some distinct advantages I would certainly give the app a go. Effective shareware apps are one oif the best reasons for using a Mac, so come on Developer, give us your sales pitch versus Teleport!

You know, I use Teleport too and it is super, however it has a lag that really drives me crazy. It appears to pause about every 20-30 seconds. I've reported it to the developer, but no help is offered. I'm using very fast machines with a Gb wired and 802.11n wireless network and switching connection methods don't seem to affect it so it appears to be dependent upon something else.Reply to This
