Thanks Dom,

Didn't work but got me part way there.

RewriteEngine On
RewriteRule (.*)\\(.*) $1/$2 [N,NE]

Works on Apache 1.3 (not sure that I need the NE, but I didn't want
the slashes getting URL escaped).

Doesn't work on Apache2 though :(

I get:

RewriteRule: cannot compile regular expression '(.*)\\(.*)'

in the error log. Bah.
