What I would do (assuming I was in the mode of sending people money for 
things I stumble across -- unlikely as has been pointed out) is search in a 
directory /trader/UDDI, etc. and GET the WSDL and other meta information i 
would need to know in order to be comfortable doing business.)

I suppose one could argue that this is a priori information, but no more so 
than doing an HTTP GET on a random url and hoping I already have the 
smarts/code to know what to do with the "stuff" I get back.

Seems to me the "problem" and hence the "solution" may be a bit easier 
using the web services approach, since more is currently "standardized" 
about directory structures and meta-information for web services. The key 
is standardizing how the meta information (contracts, protocols, 
operations, etc.) is represented and how to go about getting it in a 
uniform way.

As has been pointed out, it is quite unlikely that significant bits of 
business will be done over the web (or in real life) simply because one 
discovers an "interesting" pointer (be it a uri, a wsdl document, a 
newspaper advertisement, a yellow pages (the real phone book kind), etc.
