unless you want to bury the machine deep inside something or outside the room I see few reasons to remote control.
TFTs (used) are bargain and a wireless keyboard/mouse could reduce cable.
I have several remote control apps on my iphone and iPad.
According to my memory RDP had a much better performance than VNC - the first version of Jaadu I used on the iphone via WLAN had excellent performance as a Scope controller. You could just tip the controls and drag them.
Strangely that mode of operation lacks on the iPad version of the software (possibly a special configure I didn't find)
Anyway - this is just to back up my vote for RDP, which isn't supported 'natively' under OSX (afai understand it)
In the company I work for we used a product called Timbuktu (Netopia), which was the most easy to setup remote control application and (imho) the most powerful.
As I just checked availability I noticed the current software will still work with older clients, which really surprised me.
I'll try that out with my Scope System under Win98, as I have at least 2 multi-platform licenses.
In case it works well and you consider the product usable, you I'd gladly give you a license for free...
You're the dude who made those fine Solaris presets, aren't you ?
cheers, Tom
as a sidenote I used Timbuktu around 1987 or so to remote control a beige MacPlus over a regular phoneline...
with either a 9.6 or 19.2 kbit modem - and yes, I mean full screen graphics and it was usable.
In that regard VNC is no more than a piece of poo
The company use was to remote control a Windoze box with IBM AS400 Terminal software from 3 Macs. Perfect.
