There is a way to make wireless work for LTSP clients. The solution is
trivial, but not cheap: Netgear travel router. It comes with 2 ethernet
ports and wireless connectivity. You can connect a terminal to ethernet
port and the router transfers data over wireless. Bandwidth is an issue,
since G is not all that fast, but it is perfectly acceptable for a few
terminals.
