Opening a pidgin IM window from another program

[Michael]

Hi,

I'm writing a multi-user web-based application, and would like to be 
able to click on someone's name on an HTML page and open an IM window to 
that person, but the Pidgin command-line help does not give any 
indication as to how to specify who to open an IM window to.   I've 
looked through the Pidgin online docs at developer.pidgin.im and cannot 
find any mention there, either. 

Can anyone point me to a document that will let me know how to create a 
n HTML link like this?

Thanks,

Michael
