High traffic example SOAP services?

[Steven Czerwinski <cz...@eecs.berkeley.edu>]

Hello -

Sorry to ask such a generic question, but I'm interested in 
collecting traces of SOAP interactions for some research I'm 
doing.  Does anyone have any suggestions for example SOAP 
services that would be interesting to trace?

By interesting, I mean: (a) the message passing is a little 
complex (more than just passing a single "get stock quote" 
message), (b) the service is used or could be used in the 
real world (not so abstract that it makes no real sense), 
and (c) exists in some form that I could download/ run in my 
local environment.

I'm currently thinking of some UDDI example.. but not sure.

thanks for any suggestions you have,

Steve Czerwinski
