Not really. My understanding of what VistALink is, is just an
implementation of the client end of the RPC broker in Java instead of
Delphi. You still have to talk to the actual VistA server at some point,
and the transition from VistA RPC Broker to SOAP has to occur somewhere.
Also, writing a RPC Broker client really is not difficult, it is easy to
do in any language in an hour or so. Creating a SOAP API out of the
VistA rpcs on the other hand takes a while, you have to figure out what
every RPC is returning and accepting and create complex types that
encapsulate the data, and then pass that across. And that is just to
give you an API that is 1<->1 with the VistA RPC API, most likely not
something many would find useful (A real login session requires 6+ RPCs
and that still leaves you with no patient or user information).

As I have said on this list before, we (Medsphere) do have such a
technology that sits on a server, takes SOAP calls and returns data back
from RPC calls, wrapped up in semi-coherent data structures. We actually
have server technology that allows both SOAP and an alternate form of
communication, and the ability to seamlessly switch back and forth
between the two.
