Sorted - I dropped the string into TextWrangler and saved it with the same result, so it wasn't revXML failing to handle binary data.
A deeper dig into the web service documentation found that zip file string is base64encoded.
So, a quick decode before the save to URL binfile:... and all is well.
Best,
Keith..
