Hi Phil,
Thanks for the suggestion, but neither Hex nor base64 encoding works. Although 
I no longer get the catalogInit error from TDS, LAS complains about illegal 
characters or illegal IDs in the URL. Unidata/TDS folks: can you add support 
for ampersands in the viewer URL in a future release?
Thanks!,
