ISDN should be enough, provided you take some basic speed-enhancement
precautions.  First, turn off the desktop background/pattern and set your
desktop size/depth to be not-so-large (8-bit is a good idea).  Second, make
sure you have left Hextile, CopyRect and CoRRE switched on.  Thirdly, don't
expect it to be blazingly fast - be prepared to wait a second or two for
everything to catch up.  VNC works surprisingly well over low-bandwidth
connections, I've successfully used it over a 14.4k modem across the
Atlantic and America.  Experiment with the options until you find the best
ones for you and your connection.
