These guys sell something like PC-Anywhere or VNC, but much faster. It runs on Win9x as well as Win2K & NT. Cost is only $35. The problem is, that they do not have a WinCE client (aaagh!). So far I have had good success installing radmin on my WinME machine and then connecting to it through Win2K Terminal Server from my wireless epods. So, at the very least, that is a work-around for people who have a machine to run Win2K on but want to control a Win9x machine.
I wrote to them asking if they have any plans for a WinCE client, they were non-commital. If more people where to write them they might be more interested in support us. You can write to firstname.lastname@example.org to register your interest in a WinCE client.
