Calling PC's from the AS/400

Things have been quiet.  Here's a new question.

We had a question in our office that I thought someone might have
some insight on.  If anyone has any thoughts or can point me
somewhere, that would be great.

The Technical Challenge:

We are looking for a way to call the client from the AS/400.   
For example, when a user is accessing an application using any 
emulation package, we want to run something on their PC.  How do 
we call into their PC?  I know how to do this with an APPC connection 
but need to do this with TCP/IP connections.

I see lots of ways to call the AS/400 from a client but not vice
versa. We'd rather NOT require that they start up a client 
application that just sits on a data queue although I think that 
would work. Are there other options?

An example use of this could be to allow a button in an AS/400 based  
customer master application to e-mail to the customer.  When they 
press the button, you want to activate their PC based e-mail package. 
How does this get launched on the PC?  

Thanks for your help.
