Hmmm ... I tried that, but I just get errors back from Cocoon. Actually, 
tried <map:match type="regexp" pattern="^~([^/]*)/(.*)"> (replaced first
"[" with "^"), and here's what I get back:

Error creating the resource
  error occurred during evaluation of expression "/home/{1}/public_xml/{2}.xml"
  at position 7 Index: 0, Size: 0

Any ideas on this one?
